Remove empty line at the end of sshd-sle.pamd (bsc#1227456)- Add patch from upstream to fix proxy multiplexing mode: * 0001-upstream-fix-proxy-multiplexing-mode_-broken-when-keystroke.patch - Add patch from upstream to restore correctly sigprocmask * 0001-upstream-correctly-restore-sigprocmask-around-ppoll.patch - Add patch from upstream to fix a logic error in ObscureKeystrokeTiming that rendered this feature ineffective, allowing a passive observer to detect which network packets contained real keystrokes (bsc#1227318, CVE-2024-39894): * 0001-upstream-when-sending-ObscureKeystrokeTiming-chaff-packets_.patch- Add obsoletes for openssh-server-config-rootlogin since that package existed for a brief period of time during SLE 15 SP6/ Leap 15.6 development but even if it was removed from the repositories before GM, some users might have it in their systems from having tried a beta/RC release (boo#1227350). - Add #include in some files added by the ldap patch to fix build with gcc14 (boo#1225904). * openssh-7.7p1-ldap.patch - Remove the recommendation for openssh-server-config-rootlogin from openssh-server. Since the default for that config option was changed in SLE it's not needed anymore in SLE nor in TW (boo#1224392).- Add patch to fix a race condition in a signal handler by removing the async-signal-unsafe code (CVE-2024-6387, bsc#1226642): * fix-CVE-2024-6387.patch- Add a warning in %post of openssh-clients, openssh-server and openssh-server-config-disallow-rootlogin to warn the user if the /etc/ssh/(ssh_config.d|sshd_config.d) directories are not being used (bsc#1223486).- Only for SLE15, restore the patch file removed in Thu Feb 18 13:54:44 UTC 2021 to restore the previous behaviour from SP5 of having root password login allowed by default (fixes bsc#1223486, related to bsc#1173067): * openssh-7.7p1-allow_root_password_login.patch - Since the default value for this config option is now set to permit root to use password logins in SLE15, the openssh-server-config-rootlogin subpackage isn't useful there so we now create an openssh-server-config-disallow-rootlogin subpackage that sets the configuration the other way around than openssh-server-config-rootlogin.- openssh-8.0p1-gssapi-keyex.patch: Added missing struct initializer, added missing parameter (bsc#1222840)- Make openssh-server recommend the openssh-server-config-rootlogin package in SLE in order to keep the same behaviour of previous SPs where the PermitRootLogin default was set to yes (bsc#1221005). - Fix crypto-policies requirement to be set by openssh-server, not the config-rootlogin subpackage. - Add back %config(noreplace) tag for more config files that were already set like this in previous SPs.- Fix duplicate loading of dropins. (boo#1222467)- Update to openssh 9.6p1: = Security * ssh(1), sshd(8): implement protocol extensions to thwart the so-called "Terrapin attack" discovered by Fabian Bäumer, Marcus Brinkmann and Jörg Schwenk. This attack allows a MITM to effect a limited break of the integrity of the early encrypted SSH transport protocol by sending extra messages prior to the commencement of encryption, and deleting an equal number of consecutive messages immediately after encryption starts. A peer SSH client/server would not be able to detect that messages were deleted (bsc#1217950, CVE-2023-48795). * ssh-agent(1): when adding PKCS#11-hosted private keys while specifying destination constraints, if the PKCS#11 token returned multiple keys then only the first key had the constraints applied. Use of regular private keys, FIDO tokens and unconstrained keys are unaffected. * ssh(1): if an invalid user or hostname that contained shell metacharacters was passed to ssh(1), and a ProxyCommand, LocalCommand directive or "match exec" predicate referenced the user or hostname via %u, %h or similar expansion token, then an attacker who could supply arbitrary user/hostnames to ssh(1) could potentially perform command injection depending on what quoting was present in the user-supplied ssh_config(5) directive (bsc#1218215, CVE-2023-51385). = Potentially incompatible changes * ssh(1), sshd(8): the RFC4254 connection/channels protocol provides a TCP-like window mechanism that limits the amount of data that can be sent without acceptance from the peer. In cases where this limit was exceeded by a non-conforming peer SSH implementation, ssh(1)/sshd(8) previously discarded the extra data. From OpenSSH 9.6, ssh(1)/sshd(8) will now terminate the connection if a peer exceeds the window limit by more than a small grace factor. This change should have no effect of SSH implementations that follow the specification. = New features * ssh(1): add a %j token that expands to the configured ProxyJump hostname (or the empty string if this option is not being used) that can be used in a number of ssh_config(5) keywords. bz3610 * ssh(1): add ChannelTimeout support to the client, mirroring the same option in the server and allowing ssh(1) to terminate quiescent channels. * ssh(1), sshd(8), ssh-add(1), ssh-keygen(1): add support for reading ED25519 private keys in PEM PKCS8 format. Previously only the OpenSSH private key format was supported. * ssh(1), sshd(8): introduce a protocol extension to allow renegotiation of acceptable signature algorithms for public key authentication after the server has learned the username being used for authentication. This allows varying sshd_config(5) PubkeyAcceptedAlgorithms in a "Match user" block. * ssh-add(1), ssh-agent(1): add an agent protocol extension to allow specifying certificates when loading PKCS#11 keys. This allows the use of certificates backed by PKCS#11 private keys in all OpenSSH tools that support ssh-agent(1). Previously only ssh(1) supported this use-case. = Bugfixes * ssh(1): when deciding whether to enable the keystroke timing obfuscation, enable it only if a channel with a TTY is active. * ssh(1): switch mainloop from poll(3) to ppoll(3) and mask signals before checking flags set in signal handler. Avoids potential race condition between signaling ssh to exit and polling. bz3531 * ssh(1): when connecting to a destination with both the AddressFamily and CanonicalizeHostname directives in use, the AddressFamily directive could be ignored. bz5326 * sftp(1): correct handling of the limits@openssh.com option when the server returned an unexpected message. * A number of fixes to the PuTTY and Dropbear regress/integration tests. * ssh(1): release GSS OIDs only at end of authentication, avoiding unnecessary init/cleanup cycles. bz2982 * ssh_config(5): mention "none" is a valid argument to IdentityFile in the manual. bz3080 * scp(1): improved debugging for paths from the server rejected for not matching the client's glob(3) pattern in old SCP/RCP protocol mode. * ssh-agent(1): refuse signing operations on destination-constrained keys if a previous session-bind operation has failed. This may prevent a fail-open situation in future if a user uses a mismatched ssh(1) client and ssh-agent(1) where the client supports a key type that the agent does not support. - Update to openssh 9.5p1: = Potentially incompatible changes * ssh-keygen(1): generate Ed25519 keys by default. Ed25519 public keys are very convenient due to their small size. Ed25519 keys are specified in RFC 8709 and OpenSSH has supported them since version 6.5 (January 2014). * sshd(8): the Subsystem directive now accurately preserves quoting of subsystem commands and arguments. This may change behaviour for exotic configurations, but the most common subsystem configuration (sftp-server) is unlikely to be affected. = New features * ssh(1): add keystroke timing obfuscation to the client. This attempts to hide inter-keystroke timings by sending interactive traffic at fixed intervals (default: every 20ms) when there is only a small amount of data being sent. It also sends fake "chaff" keystrokes for a random interval after the last real keystroke. These are controlled by a new ssh_config ObscureKeystrokeTiming keyword. * ssh(1), sshd(8): Introduce a transport-level ping facility. This adds a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to implement a ping capability. These messages use numbers in the "local extensions" number space and are advertised using a "ping@openssh.com" ext-info message with a string version number of "0". * sshd(8): allow override of Subsystem directives in sshd Match blocks. = Bugfixes * scp(1): fix scp in SFTP mode recursive upload and download of directories that contain symlinks to other directories. In scp mode, the links would be followed, but in SFTP mode they were not. bz3611 * ssh-keygen(1): handle cr+lf (instead of just cr) line endings in sshsig signature files. * ssh(1): interactive mode for ControlPersist sessions if they originally requested a tty. * sshd(8): make PerSourceMaxStartups first-match-wins * sshd(8): limit artificial login delay to a reasonable maximum (5s) and don't delay at all for the "none" authentication mechanism. bz3602 * sshd(8): Log errors in kex_exchange_identification() with level verbose instead of error to reduce preauth log spam. All of those get logged with a more generic error message by sshpkt_fatal(). * sshd(8): correct math for ClientAliveInterval that caused the probes to be sent less frequently than configured. * ssh(1): fix regression in OpenSSH 9.4 (mux.c r1.99) that caused multiplexed sessions to ignore SIGINT under some circumstances. - Update to openssh 9.4p1: = Potentially incompatible changes * This release removes support for older versions of libcrypto. OpenSSH now requires LibreSSL >= 3.1.0 or OpenSSL >= 1.1.1. Note that these versions are already deprecated by their upstream vendors. * ssh-agent(1): PKCS#11 modules must now be specified by their full paths. Previously dlopen(3) could search for them in system library directories. = New features * ssh(1): allow forwarding Unix Domain sockets via ssh -W. * ssh(1): add support for configuration tags to ssh(1). This adds a ssh_config(5) "Tag" directive and corresponding "Match tag" predicate that may be used to select blocks of configuration similar to the pf.conf(5) keywords of the same name. * ssh(1): add a "match localnetwork" predicate. This allows matching on the addresses of available network interfaces and may be used to vary the effective client configuration based on network location. * ssh(1), sshd(8), ssh-keygen(1): infrastructure support for KRL extensions. This defines wire formats for optional KRL extensions and implements parsing of the new submessages. No actual extensions are supported at this point. * sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now accept two additional %-expansion sequences: %D which expands to the routing domain of the connected session and %C which expands to the addresses and port numbers for the source and destination of the connection. * ssh-keygen(1): increase the default work factor (rounds) for the bcrypt KDF used to derive symmetric encryption keys for passphrase protected key files by 50%. = Bugfixes * ssh-agent(1): improve isolation between loaded PKCS#11 modules by running separate ssh-pkcs11-helpers for each loaded provider. * ssh(1): make -f (fork after authentication) work correctly with multiplexed connections, including ControlPersist. bz3589 bz3589 * ssh(1): make ConnectTimeout apply to multiplexing sockets and not just to network connections. * ssh-agent(1), ssh(1): improve defences against invalid PKCS#11 modules being loaded by checking that the requested module contains the required symbol before loading it. * sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand appears before it in sshd_config. Since OpenSSH 8.7 the AuthorizedPrincipalsCommand directive was incorrectly ignored in this situation. bz3574 * sshd(8), ssh(1), ssh-keygen(1): remove vestigal support for KRL signatures When the KRL format was originally defined, it included support for signing of KRL objects. However, the code to sign KRLs and verify KRL signatues was never completed in OpenSSH. This release removes the partially-implemented code to verify KRLs. All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in KRL files. * All: fix a number of memory leaks and unreachable/harmless integer overflows. * ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11 modules; GHPR406 * sshd(8), ssh(1): better validate CASignatureAlgorithms in ssh_config and sshd_config. Previously this directive would accept certificate algorithm names, but these were unusable in practice as OpenSSH does not support CA chains. bz3577 * ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature algorithms that are valid for CA signing. Previous behaviour was to list all signing algorithms, including certificate algorithms. * ssh-keyscan(1): gracefully handle systems where rlimits or the maximum number of open files is larger than INT_MAX; bz3581 * ssh-keygen(1): fix "no comment" not showing on when running `ssh-keygen -l` on multiple keys where one has a comment and other following keys do not. bz3580 * scp(1), sftp(1): adjust ftruncate() logic to handle servers that reorder requests. Previously, if the server reordered requests then the resultant file would be erroneously truncated. * ssh(1): don't incorrectly disable hostname canonicalization when CanonicalizeHostname=yes and ProxyJump was expicitly set to "none". bz3567 * scp(1): when copying local->remote, check that the source file exists before opening an SFTP connection to the server. Based on GHPR#370 - Dropped patches: * cb4ed12f.patch - implemented upstream. - Rebased patches: * openssh-7.7p1-fips.patch * openssh-7.8p1-role-mls.patch * openssh-8.0p1-gssapi-keyex.patch - Add patches from obs: * Mon Mar 4 09:57:06 UTC 2024 - Pedro Monreal - Add crypto-policies support [bsc#1211301] * Add patches: - openssh-9.6p1-crypto-policies.patch - openssh-9.6p1-crypto-policies-man.patch- Rebase openssh-7.7p1-fips.patch (bsc#1221928) Remove OPENSSL_HAVE_EVPGCM-ifdef, which is no longer supported by upstream- Use %config(noreplace) for sshd_config .

This informs systemd-logind of the login TTY and prevents having to parse utmp, which is deprecated by glibc.- Update to openssh 9.3p2 (bsc#1213504, CVE-2023-38408): = Security * Fix CVE-2023-38408 - a condition where specific libaries loaded via ssh-agent(1)'s PKCS#11 support could be abused to achieve remote code execution via a forwarded agent socket if the following conditions are met: * Exploitation requires the presence of specific libraries on the victim system. * Remote exploitation requires that the agent was forwarded to an attacker-controlled system. Exploitation can also be prevented by starting ssh-agent(1) with an empty PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring an allowlist that contains only specific provider libraries. This vulnerability was discovered and demonstrated to be exploitable by the Qualys Security Advisory team. In addition to removing the main precondition for exploitation, this release removes the ability for remote ssh-agent(1) clients to load PKCS#11 modules by default (see below). = Potentially-incompatible changes * ssh-agent(8): the agent will now refuse requests to load PKCS#11 modules issued by remote clients by default. A flag has been added to restore the previous behaviour "-Oallow-remote-pkcs11". Note that ssh-agent(8) depends on the SSH client to identify requests that are remote. The OpenSSH >=8.9 ssh(1) client does this, but forwarding access to an agent socket using other tools may circumvent this restriction.- openssh-7.7p1-fips_checks.patch: close the right filedescriptor to avoid fd leads, and also close fdh in read_hmac (bsc#1209536)- Update to openssh 9.3p1: = Security * ssh-add(1): when adding smartcard keys to ssh-agent(1) with the per-hop destination constraints (ssh-add -h ...) added in OpenSSH 8.9, a logic error prevented the constraints from being communicated to the agent. This resulted in the keys being added without constraints. The common cases of non-smartcard keys and keys without destination constraints are unaffected. This problem was reported by Luci Stanescu. * ssh(1): Portable OpenSSH provides an implementation of the getrrsetbyname(3) function if the standard library does not provide it, for use by the VerifyHostKeyDNS feature. A specifically crafted DNS response could cause this function to perform an out-of-bounds read of adjacent stack data, but this condition does not appear to be exploitable beyond denial-of- service to the ssh(1) client. The getrrsetbyname(3) replacement is only included if the system's standard library lacks this function and portable OpenSSH was not compiled with the ldns library (--with-ldns). getrrsetbyname(3) is only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This problem was found by the Coverity static analyzer. = New features * ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when outputting SSHFP fingerprints to allow algorithm selection. bz3493 * sshd(8): add a `sshd -G` option that parses and prints the effective configuration without attempting to load private keys and perform other checks. This allows usage of the option before keys have been generated and for configuration evaluation and verification by unprivileged users. = Bugfixes * scp(1), sftp(1): fix progressmeter corruption on wide displays; bz3534 * ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability of private keys as some systems are starting to disable RSA/SHA1 in libcrypto. * sftp-server(8): fix a memory leak. GHPR363 * ssh(1), sshd(8), ssh-keyscan(1): remove vestigal protocol compatibility code and simplify what's left. * Fix a number of low-impact Coverity static analysis findings. These include several reported via bz2687 * ssh_config(5), sshd_config(5): mention that some options are not first-match-wins. * Rework logging for the regression tests. Regression tests will now capture separate logs for each ssh and sshd invocation in a test. * ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage says it should; bz3532. * ssh(1): ensure that there is a terminating newline when adding a new entry to known_hosts; bz3529 = Portability * sshd(8): harden Linux seccomp sandbox. Move to an allowlist of mmap(2), madvise(2) and futex(2) flags, removing some concerning kernel attack surface. * sshd(8): improve Linux seccomp-bpf sandbox for older systems; bz3537 - Update to openssh 9.2p1: = Security * sshd(8): fix a pre-authentication double-free memory fault introduced in OpenSSH 9.1. This is not believed to be exploitable, and it occurs in the unprivileged pre-auth process that is subject to chroot(2) and is further sandboxed on most major platforms. * ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option would ignore its first argument unless it was one of the special keywords "any" or "none", causing the permission list to fail open if only one permission was specified. bz3515 * ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs options were enabled, and the system/libc resolver did not check that names in DNS responses were valid, then use of these options could allow an attacker with control of DNS to include invalid characters (possibly including wildcards) in names added to known_hosts files when they were updated. These names would still have to match the CanonicalizePermittedCNAMEs allow-list, so practical exploitation appears unlikely. = Potentially-incompatible changes * ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that controls whether the client-side ~C escape sequence that provides a command-line is available. Among other things, the ~C command-line could be used to add additional port-forwards at runtime. This option defaults to "no", disabling the ~C command-line that was previously enabled by default. Turning off the command-line allows platforms that support sandboxing of the ssh(1) client (currently only OpenBSD) to use a stricter default sandbox policy. = New features * sshd(8): add support for channel inactivity timeouts via a new sshd_config(5) ChannelTimeout directive. This allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. * sshd(8): add a sshd_config UnusedConnectionTimeout option to terminate client connections that have no open channels for a length of time. This complements the ChannelTimeout option above. * sshd(8): add a -V (version) option to sshd like the ssh client has. * ssh(1): add a "Host" line to the output of ssh -G showing the original hostname argument. bz3343 * scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol parameters: the copy buffer length and the number of in-flight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) only. This makes them available in both SFTP protocol clients using the same option character sequence. * ssh-keyscan(1): allow scanning of complete CIDR address ranges, e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then it will be expanded to all possible addresses in the range including the all-0s and all-1s addresses. bz#976 * ssh(1): support dynamic remote port forwarding in escape command-line's -R processing. bz#3499 = Bugfixes * ssh(1): when restoring non-blocking mode to stdio fds, restore exactly the flags that ssh started with and don't just clobber them with zero, as this could also remove the append flag from the set. bz3523 * ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none and a hostkey in one of the system known hosts file changes. * scp(1): switch scp from using pipes to a socket-pair for communication with its ssh sub-processes, matching how sftp(1) operates. * sshd(8): clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist. * ssh(1): warn if no host keys for hostbased auth can be loaded. * sshd(8): Add server debugging for hostbased auth that is queued and sent to the client after successful authentication, but also logged to assist in diagnosis of HostbasedAuthentication problems. bz3507 * ssh(1): document use of the IdentityFile option as being usable to list public keys as well as private keys. GHPR352 * sshd(8): check for and disallow MaxStartups values less than or equal to zero during config parsing, rather than failing later at runtime. bz3489 * ssh-keygen(1): fix parsing of hex cert expiry times specified on the command-line when acting as a CA. * scp(1): when scp(1) is using the SFTP protocol for transport (the default), better match scp/rcp's handling of globs that don't match the globbed characters but do match literally (e.g. trying to transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode would not match these pathnames but legacy scp/rcp mode would. bz3488 * ssh-agent(1): document the "-O no-restrict-websafe" command-line option. * ssh(1): honour user's umask(2) if it is more restrictive then the ssh default (022). = Portability * sshd(8): allow writev(2) in the Linux seccomp sandbox. This seems to be used by recent glibcs at least in some configurations during error conditions. bz3512. * sshd(8): simply handling of SSH_CONNECTION PAM env var, removing global variable and checking the return value from pam_putenv. bz3508 * sshd(8): disable SANDBOX_SECCOMP_FILTER_DEBUG that was mistakenly enabled during the OpenSSH 9.1 release cycle. * misc: update autotools and regenerate the config files using the latest autotools * all: use -fzero-call-used-regs=used on clang 15 instead of - fzero-call-used-reg=all, as some versions of clang 15 have miscompile code when it was enabled. bz3475 * sshd(8): defer PRNG seeding until after the initial closefrom(2) call. PRNG seeding will initialize OpenSSL, and some engine providers (e.g. Intel's QAT) will open descriptors for their own use that closefrom(2) could clobber. bz3483 * misc: in the poll(2)/ppoll(2) compatibility code, avoid assuming the layout of fd_set. * sftp-server(8), ssh-agent(1): fix ptrace(2) disabling on older FreeBSD kernels. Some versions do not support using id 0 to refer to the current PID for procctl, so try again with getpid() explicitly before failing. * configure.ac: fix -Wstrict-prototypes in configure test code. Clang 16 now warns on this and legacy prototypes will be removed in C23. GHPR355 * configure.ac: fix setres*id checks to work with clang-16. glibc has the prototypes for setresuid behind _GNU_SOURCE, and clang 16 will error out on implicit function definitions. bz3497 - Update to openssh 9.1p1: = Security * ssh-keyscan(1): fix a one-byte overflow in SSH- banner processing. Reported by Qualys * ssh-keygen(1): double free() in error path of file hashing step in signing/verify code; GHPR333 * ssh-keysign(8): double-free in error path introduced in openssh-8.9 = Potentially-incompatible changes * The portable OpenSSH project now signs commits and release tags using git's recent SSH signature support. The list of developer signing keys is included in the repository as .git_allowed_signers and is cross-signed using the PGP key that is still used to sign release artifacts: https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/RELEASE_KEY.asc * ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config are now first-match-wins to match other directives. Previously if an environment variable was multiply specified the last set value would have been used. bz3438 * ssh-keygen(8): ssh-keygen -A (generate all default host key types) will no longer generate DSA keys, as these are insecure and have not been used by default for some years. = New features * ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum RSA key length. Keys below this length will be ignored for user authentication and for host authentication in sshd(8). ssh(1) will terminate a connection if the server offers an RSA key that falls below this limit, as the SSH protocol does not include the ability to retry a failed key exchange. * sftp-server(8): add a "users-groups-by-id@openssh.com" extension request that allows the client to obtain user/group names that correspond to a set of uids/gids. * sftp(1): use "users-groups-by-id@openssh.com" sftp-server extension (when available) to fill in user/group names for directory listings. * sftp-server(8): support the "home-directory" extension request defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with the existing "expand-path@openssh.com", but some other clients support it. * ssh-keygen(1), sshd(8): allow certificate validity intervals, sshsig verification times and authorized_keys expiry-time options to accept dates in the UTC time zone in addition to the default of interpreting them in the system time zone. YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed with a 'Z' character. Also allow certificate validity intervals to be specified in raw seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This is intended for use by regress tests and other tools that call ssh-keygen as part of a CA workflow. bz3468 * sftp(1): allow arguments to the sftp -D option, e.g. sftp -D "/usr/libexec/sftp-server -el debug3" * ssh-keygen(1): allow the existing -U (use agent) flag to work with "-Y sign" operations, where it will be interpreted to require that the private keys is hosted in an agent; bz3429 = Bugfixes * ssh-keygen(1): implement the "verify-required" certificate option. This was already documented when support for user-verified FIDO keys was added, but the ssh-keygen(1) code was missing. * ssh-agent(1): hook up the restrict_websafe command-line flag; previously the flag was accepted but never actually used. * sftp(1): improve filename tab completions: never try to complete names to non-existent commands, and better match the completion type (local or remote filename) against the argument position being completed. * ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key handling, especially relating to keys that request user-verification. These should reduce the number of unnecessary PIN prompts for keys that support intrinsic user verification. GHPR302, GHPR329 * ssh-keygen(1): when enrolling a FIDO resident key, check if a credential with matching application and user ID strings already exists and, if so, prompt the user for confirmation before overwriting the credential. GHPR329 * sshd(8): improve logging of errors when opening authorized_keys files. bz2042 * ssh(1): avoid multiplexing operations that could cause SIGPIPE from causing the client to exit early. bz3454 * ssh_config(5), sshd_config(5): clarify that the RekeyLimit directive applies to both transmitted and received data. GHPR328 * ssh-keygen(1): avoid double fclose() in error path. * sshd(8): log an error if pipe() fails while accepting a connection. bz3447 * ssh(1), ssh-keygen(1): fix possible NULL deref when built without FIDO support. bz3443 * ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage. GHPR294. * sshd(8): ensure that authentication passwords are cleared from memory in error paths. GHPR286 * ssh(1), ssh-agent(1): avoid possibility of notifier code executing kill(-1). GHPR286 * ssh_config(5): note that the ProxyJump directive also accepts the same tokens as ProxyCommand. GHPR305. * scp(1): do not not ftruncate(3) files early when in sftp mode. The previous behaviour of unconditionally truncating the destination file would cause "scp ~/foo localhost:foo" and the reverse "scp localhost:foo ~/foo" to delete all the contents of their destination. bz3431 * ssh-keygen(1): improve error message when 'ssh-keygen -Y sign' is unable to load a private key; bz3429 * sftp(1), scp(1): when performing operations that glob(3) a remote path, ensure that the implicit working directory used to construct that path escapes glob(3) characters. This prevents glob characters from being processed in places they shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation treat the path "/tmp/a*" literally and not attempt to expand it. * ssh(1), sshd(8): be stricter in which characters will be accepted in specifying a mask length; allow only 0-9. GHPR278 * ssh-keygen(1): avoid printing hash algorithm twice when dumping a KRL * ssh(1), sshd(8): continue running local I/O for open channels during SSH transport rekeying. This should make ~-escapes work in the client (e.g. to exit) if the connection happened to have stalled during a rekey event. * ssh(1), sshd(8): avoid potential poll() spin during rekeying * Further hardening for sshbuf internals: disallow "reparenting" a hierarchical sshbuf and zero the entire buffer if reallocation fails. GHPR287 = Portability * ssh(1), ssh-keygen(1), sshd(8): automatically enable the built-in FIDO security key support if libfido2 is found and usable, unless --without-security-key-builtin was requested. * ssh(1), ssh-keygen(1), sshd(8): many fixes to make the WinHello FIDO device usable on Cygwin. The windows://hello FIDO device will be automatically used by default on this platform unless requested otherwise, or when probing resident FIDO credentials (an operation not currently supported by WinHello). * Portable OpenSSH: remove workarounds for obsolete and unsupported versions of OpenSSL libcrypto. In particular, this release removes fallback support for OpenSSL that lacks AES-CTR or AES-GCM. Those AES cipher modes were added to OpenSSL prior to the minimum version currently supported by OpenSSH, so this is not expected to impact any currently supported configurations. * sshd(8): fix SANDBOX_SECCOMP_FILTER_DEBUG on current Linux/glibc * All: resync and clean up internal CSPRNG code. * scp(1), sftp(1), sftp-server(8): avoid linking these programs with unnecessary libraries. They are no longer linked against libz and libcrypto. This may be of benefit to space constrained systems using any of those components in isolation. * sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox architectures. * configure: remove special casing of crypt(). configure will no longer search for crypt() in libcrypto, as it was removed from there years ago. configure will now only search libc and libcrypt. * configure: refuse to use OpenSSL 3.0.4 due to potential RCE in its RSA implementation (CVE-2022-2274) on x86_64. * All: request 1.1x API compatibility for OpenSSL >=3.x; GHPR322 * ssh(1), ssh-keygen(1), sshd(8): fix a number of missing includes required by the XMSS code on some platforms. * sshd(8): cache timezone data in capsicum sandbox. - Update to openssh 9.0p1: = Potentially-incompatible changes * This release switches scp(1) from using the legacy scp/rcp protocol to using the SFTP protocol by default. Legacy scp/rcp performs wildcard expansion of remote filenames (e.g. "scp host:* .") through the remote shell. This has the side effect of requiring double quoting of shell meta-characters in file names included on scp(1) command-lines, otherwise they could be interpreted as shell commands on the remote side. This creates one area of potential incompatibility: scp(1) when using the SFTP protocol no longer requires this finicky and brittle quoting, and attempts to use it may cause transfers to fail. We consider the removal of the need for double-quoting shell characters in file names to be a benefit and do not intend to introduce bug-compatibility for legacy scp/rcp in scp(1) when using the SFTP protocol. Another area of potential incompatibility relates to the use of remote paths relative to other user's home directories, for example - "scp host:~user/file /tmp". The SFTP protocol has no native way to expand a ~user path. However, sftp-server(8) in OpenSSH 8.7 and later support a protocol extension "expand-path@openssh.com" to support this. In case of incompatibility, the scp(1) client may be instructed to use the legacy scp/rcp using the -O flag. = New features * ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key exchange method by default ("sntrup761x25519-sha512@openssh.com"). The NTRU algorithm is believed to resist attacks enabled by future quantum computers and is paired with the X25519 ECDH key exchange (the previous default) as a backstop against any weaknesses in NTRU Prime that may be discovered in the future. The combination ensures that the hybrid exchange offers at least as good security as the status quo. We are making this change now (i.e. ahead of cryptographically- relevant quantum computers) to prevent "capture now, decrypt later" attacks where an adversary who can record and store SSH session ciphertext would be able to decrypt it once a sufficiently advanced quantum computer is available. * sftp-server(8): support the "copy-data" extension to allow server-side copying of files/data, following the design in draft-ietf-secsh-filexfer-extensions-00. bz2948 * sftp(1): add a "cp" command to allow the sftp client to perform server-side file copies. = Bugfixes * ssh(1), sshd(8): upstream: fix poll(2) spin when a channel's output fd closes without data in the channel buffer. bz3405 and bz3411 * sshd(8): pack pollfd array in server listen/accept loop. Could cause the server to hang/spin when MaxStartups > RLIMIT_NOFILE * ssh-keygen(1): avoid NULL deref via the find-principals and check-novalidate operations. bz3409 and GHPR307 respectively. * scp(1): fix a memory leak in argument processing. bz3404 * sshd(8): don't try to resolve ListenAddress directives in the sshd re-exec path. They are unused after re-exec and parsing errors (possible for example if the host's network configuration changed) could prevent connections from being accepted. * sshd(8): when refusing a public key authentication request from a client for using an unapproved or unsupported signature algorithm include the algorithm name in the log message to make debugging easier. = Portability * sshd(8): refactor platform-specific locked account check, fixing an incorrect free() on platforms with both libiaf and shadow passwords (probably only Unixware) GHPR284, * ssh(1), sshd(8): Fix possible integer underflow in scan_scaled(3) parsing of K/M/G/etc quantities. bz#3401. * sshd(8): provide killpg implementation (mostly for Tandem NonStop) GHPR301. * Check for missing ftruncate prototype. GHPR301 * sshd(8): default to not using sandbox when cross compiling. On most systems poll(2) does not work when the number of FDs is reduced with setrlimit, so assume it doesn't when cross compiling and we can't run the test. bz#3398. * sshd(8): allow ppoll_time64 in seccomp sandbox. Should fix sandbox violations on some (at least i386 and armhf) 32bit Linux platforms. bz#3396. * Improve detection of -fzero-call-used-regs=all support in configure script. - Add patch that explicitly adds -lz in Makefile.in to some binaries which need it: * fix-missing-lz.patch - Rebase patches: * openssh-7.7p1-fips.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-pam_check_locks.patch * openssh-7.7p1-seccomp_ipc_flock.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-7.7p1-systemd-notify.patch * openssh-8.0p1-gssapi-keyex.patch * openssh-8.1p1-audit.patch * openssh-8.1p1-ed25519-use-openssl-rng.patch * openssh-8.4p1-vendordir.patch * openssh-reenable-dh-group14-sha1-default.patch * openssh-whitelist-syscalls.patch * wtmpdb.patch - Fix setting libexec dir in the LDAP patch. - Fix build in Leap 15.x which doesn't use %{_distconfdir}- Add _multibuild to define 2nd spec file as additional flavor. Eliminates the need for source package links in OBS.- wtmpdb.patch: add support for wtmpdb to sshd [jsc#PED-3144]- Revert addition of openssh-dbus.sh, openssh-dbus.csh, openssh-dbus.fish: This caused invalid and irrelevant environment assignments (bsc#1207014).- Rename sshd.pamd to sshd-sle.pamd and fix order of pam_keyinit - Add new sshd.pamd including postlogin-* config files- Remove BuildRequires for libtirpc, we don't use it- Remove pam_lastlog from sshd PAM config. sshd is doing the same, too, which leads to e.g. duplicate entries in wtmp [bsc#1208243]- Adapt OpenSSH to build with OpenSSL 3, use new KDF API (bsc#1205042) Add openssh-openssl-3.patch- limit to openssl < 3.0 as this version is not compatible (bsc#1205042) next version update will fix it- Update openssh-8.1p1-audit.patch: Merge fix for race condition (bsc#1115550, bsc#1174162). - Add openssh-do-not-send-empty-message.patch, which prevents superfluous newlines with empty MOTD files (bsc#1192439).- Use %_pam_vendordir- openssh-8.4p1-ssh_config_d.patch: admin overrides should take priority (listed first) over package defaults- Add openssh-dbus.sh, openssh-dbus.csh, openssh-dbus.fish: Make ssh connections update their dbus environment (bsc#1179465).- Add openssh-do-not-send-empty-message.patch: Prevent empty messages from being sent. This avoids a superfluous new line (bsc#1192439).- read ssh and sshd config file also from /usr/etc - add openssh-server-config-rootlogin subpackage that enabled PermitRootLogin- Version update to 8.9p1: = Security * sshd(8): fix an integer overflow in the user authentication path that, in conjunction with other logic errors, could have yielded unauthenticated access under difficult to exploit conditions. This situation is not exploitable because of independent checks in the privilege separation monitor. Privilege separation has been enabled by default in since openssh-3.2.2 (released in 2002) and has been mandatory since openssh-7.5 (released in 2017). Moreover, portable OpenSSH has used toolchain features available in most modern compilers to abort on signed integer overflow since openssh-6.5 (released in 2014). Thanks to Malcolm Stagg for finding and reporting this bug. = Potentially-incompatible changes * sshd(8), portable OpenSSH only: this release removes in-built support for MD5-hashed passwords. If you require these on your system then we recommend linking against libxcrypt or similar. * This release modifies the FIDO security key middleware interface and increments SSH_SK_VERSION_MAJOR. = New features * ssh(1), sshd(8), ssh-add(1), ssh-agent(1): add a system for restricting forwarding and use of keys added to ssh-agent(1) A detailed description of the feature is available at https://www.openssh.com/agent-restrict.html and the protocol extensions are documented in the PROTOCOL and PROTOCOL.agent files in the source release. * ssh(1), sshd(8): add the sntrup761x25519-sha512@openssh.com hybrid ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the default KEXAlgorithms list (after the ECDH methods but before the prime-group DH ones). The next release of OpenSSH is likely to make this key exchange the default method. * ssh-keygen(1): when downloading resident keys from a FIDO token, pass back the user ID that was used when the key was created and append it to the filename the key is written to (if it is not the default). Avoids keys being clobbered if the user created multiple resident keys with the same application string but different user IDs. * ssh-keygen(1), ssh(1), ssh-agent(1): better handling for FIDO keys on tokens that provide user verification (UV) on the device itself, including biometric keys, avoiding unnecessary PIN prompts. * ssh-keygen(1): add "ssh-keygen -Y match-principals" operation to perform matching of principals names against an allowed signers file. To be used towards a TOFU model for SSH signatures in git. * ssh-add(1), ssh-agent(1): allow pin-required FIDO keys to be added to ssh-agent(1). $SSH_ASKPASS will be used to request the PIN at authentication time. * ssh-keygen(1): allow selection of hash at sshsig signing time (either sha512 (default) or sha256). * ssh(1), sshd(8): read network data directly to the packet input buffer instead of indirectly via a small stack buffer. Provides a modest performance improvement. * ssh(1), sshd(8): read data directly to the channel input buffer, providing a similar modest performance improvement. * ssh(1): extend the PubkeyAuthentication configuration directive to accept yes|no|unbound|host-bound to allow control over one of the protocol extensions used to implement agent-restricted keys. = Bugfixes * sshd(8): document that CASignatureAlgorithms, ExposeAuthInfo and PubkeyAuthOptions can be used in a Match block. PR277. * sshd(8): fix possible string truncation when constructing paths to .rhosts/.shosts files with very long user home directory names. * ssh-keysign(1): unbreak for KEX algorithms that use SHA384/512 exchange hashes * ssh(1): don't put the TTY into raw mode when SessionType=none, avoids ^C being unable to kill such a session. bz3360 * scp(1): fix some corner-case bugs in SFTP-mode handling of ~-prefixed paths. * ssh(1): unbreak hostbased auth using RSA keys. Allow ssh(1) to select RSA keys when only RSA/SHA2 signature algorithms are configured (this is the default case). Previously RSA keys were not being considered in the default case. * ssh-keysign(1): make ssh-keysign use the requested signature algorithm and not the default for the key type. Part of unbreaking hostbased auth for RSA/SHA2 keys. * ssh(1): stricter UpdateHostkey signature verification logic on the client- side. Require RSA/SHA2 signatures for RSA hostkeys except when RSA/SHA1 was explicitly negotiated during initial KEX; bz3375 * ssh(1), sshd(8): fix signature algorithm selection logic for UpdateHostkeys on the server side. The previous code tried to prefer RSA/SHA2 for hostkey proofs of RSA keys, but missed some cases. This will use RSA/SHA2 signatures for RSA keys if the client proposed these algorithms in initial KEX. bz3375 * All: convert all uses of select(2)/pselect(2) to poll(2)/ppoll(2). This includes the mainloops in ssh(1), ssh-agent(1), ssh-agent(1) and sftp-server(8), as well as the sshd(8) listen loop and all other FD read/writability checks. On platforms with missing or broken poll(2)/ppoll(2) syscalls a select(2)-based compat shim is available. * ssh-keygen(1): the "-Y find-principals" command was verifying key validity when using ca certs but not with simple key lifetimes within the allowed signers file. * ssh-keygen(1): make sshsig verify-time argument parsing optional * sshd(8): fix truncation in rhosts/shosts path construction. * ssh(1), ssh-agent(1): avoid xmalloc(0) for PKCS#11 keyid for ECDSA keys (we already did this for RSA keys). Avoids fatal errors for PKCS#11 libraries that return empty keyid, e.g. Microchip ATECC608B "cryptoauthlib"; bz#3364 * ssh(1), ssh-agent(1): improve the testing of credentials against inserted FIDO: ask the token whether a particular key belongs to it in cases where the token supports on-token user-verification (e.g. biometrics) rather than just assuming that it will accept it. Will reduce spurious "Confirm user presence" notifications for key handles that relate to FIDO keys that are not currently inserted in at least some cases. bz3366 * ssh(1), sshd(8): correct value for IPTOS_DSCP_LE. It needs to allow for the preceding two ECN bits. bz#3373 * ssh-keygen(1): add missing -O option to usage() for the "-Y sign" option. * ssh-keygen(1): fix a NULL deref when using the find-principals function, when matching an allowed_signers line that contains a namespace restriction, but no restriction specified on the command-line * ssh-agent(1): fix memleak in process_extension(); oss-fuzz issue #42719 * ssh(1): suppress "Connection to xxx closed" messages when LogLevel is set to "error" or above. bz3378 * ssh(1), sshd(8): use correct zlib flags when inflate(3)-ing compressed packet data. bz3372 * scp(1): when recursively transferring files in SFTP mode, create the destination directory if it doesn't already exist to match scp(1) in legacy RCP mode behaviour. * scp(1): many improvements in error message consistency between scp(1) in SFTP mode vs legacy RCP mode. * sshd(8): fix potential race in SIGTERM handling PR289 * ssh(1), ssh(8): since DSA keys are deprecated, move them to the end of the default list of public keys so that they will be tried last. PR295 * ssh-keygen(1): allow 'ssh-keygen -Y find-principals' to match wildcard principals in allowed_signers files = Portability * ssh(1), sshd(8): don't trust closefrom(2) on Linux. glibc's implementation does not work in a chroot when the kernel does not have close_range(2). It tries to read from /proc/self/fd and when that fails dies with an assertion of sorts. Instead, call close_range(2) directly from our compat code and fall back if that fails. bz#3349, * OS X poll(2) is broken; use compat replacement. For character- special devices like /dev/null, Darwin's poll(2) returns POLLNVAL when polled with POLLIN. Apparently this is Apple bug 3710161 - not public but a websearch will find other OSS projects rediscovering it periodically since it was first identified in 2005. * Correct handling of exceptfds/POLLPRI in our select(2)-based poll(2)/ppoll(2) compat implementation. * Cygwin: correct checking of mbstowcs() return value. * Add a basic SECURITY.md that refers people to the openssh.com website. * Enable additional compiler warnings and toolchain hardening flags, including -Wbitwise-instead-of-logical, -Wmisleading-indentation, - fzero-call-used-regs and -ftrivial-auto-var-init. * HP/UX. Use compat getline(3) on HP-UX 10.x, where the libc version is not reliable. - Rebased patches: * openssh-7.7p1-ldap.patch * openssh-8.0p1-gssapi-keyex.patch * openssh-8.1p1-audit.patch * openssh-8.4p1-vendordir.patch * openssh-reenable-dh-group14-sha1-default.patch- Add openssh-CVE-2021-28041-agent-double-free.patch (bsc#1183137, CVE-2021-28041), from upstream.- Add openssh-bsc1190975-CVE-2021-41617-authorizedkeyscommand.patch (bsc#1190975, CVE-2021-41617), backported from upstream by Ali Abdallah.- Version update to 8.8p1: = Security * sshd(8) from OpenSSH 6.2 through 8.7 failed to correctly initialise supplemental groups when executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser directive has been set to run the command as a different user. Instead these commands would inherit the groups that sshd(8) was started with. Depending on system configuration, inherited groups may allow AuthorizedKeysCommand/AuthorizedPrincipalsCommand helper programs to gain unintended privilege. Neither AuthorizedKeysCommand nor AuthorizedPrincipalsCommand are enabled by default in sshd_config(5). = Potentially-incompatible changes * This release disables RSA signatures using the SHA-1 hash algorithm by default. This change has been made as the SHA-1 hash algorithm is cryptographically broken, and it is possible to create chosen-prefix hash collisions for argv conversion. Multiple backslashes were not being dequoted correctly and quoted space in the middle of a string was being incorrectly split. GHPR223 * ssh(1): return non-zero exit status when killed by signal; bz#3281 * sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum packet size. Also handle zero-length reads that are not explicitly banned by the spec. - Additional changes from 8.5p1 release: = Security * ssh-agent(1): fixed a double-free memory corruption that was introduced in OpenSSH 8.2 . We treat all such memory faults as potentially exploitable. This bug could be reached by an attacker with access to the agent socket. = Potentially-incompatible changes * ssh(1), sshd(8): this release changes the first-preference signature algorithm from ECDSA to ED25519. * ssh(1), sshd(8): set the TOS/DSCP specified in the configuration for interactive use prior to TCP connect. The connection phase of the SSH session is time-sensitive and often explicitly interactive. The ultimate interactive/bulk TOS/DSCP will be set after authentication completes. * ssh(1), sshd(8): remove the pre-standardization cipher rijndael-cbc@lysator.liu.se. It is an alias for aes256-cbc before it was standardized in RFC4253 (2006), has been deprecated and disabled by default since OpenSSH 7.2 (2016) and was only briefly documented in ssh.1 in 2001. * ssh(1), sshd(8): update/replace the experimental post-quantum hybrid key exchange method based on Streamlined NTRU Prime coupled with X25519. The previous sntrup4591761x25519-sha512@tinyssh.org method is replaced with sntrup761x25519-sha512@openssh.com. * ssh(1): disable CheckHostIP by default. It provides insignificant benefits while making key rotation significantly more difficult, especially for hosts behind IP-based load-balancers. = New features * ssh(1): this release enables UpdateHostkeys by default subject to some conservative preconditions: - The key was matched in the UserKnownHostsFile (and not in the GlobalKnownHostsFile). - The same key does not exist under another name. - A certificate host key is not in use. - known_hosts contains no matching wildcard hostname pattern. - VerifyHostKeyDNS is not enabled. - The default UserKnownHostsFile is in use. * ssh(1), sshd(8): add a new LogVerbose configuration directive for that allows forcing maximum debug logging by file/function/line pattern-lists. * ssh(1): when prompting the user to accept a new hostkey, display any other host names/addresses already associated with the key. * ssh(1): allow UserKnownHostsFile=none to indicate that no known_hosts file should be used to identify host keys. * ssh(1): add a ssh_config KnownHostsCommand option that allows the client to obtain known_hosts data from a command in addition to the usual files. * ssh(1): add a ssh_config PermitRemoteOpen option that allows the client to restrict the destination when RemoteForward is used with SOCKS. * ssh(1): for FIDO keys, if a signature operation fails with a "incorrect PIN" reason and no PIN was initially requested from the user, then request a PIN and retry the operation. This supports some biometric devices that fall back to requiring PIN when reading of the biometric failed, and devices that require PINs for all hosted credentials. * sshd(8): implement client address-based rate-limiting via new sshd_config(5) PerSourceMaxStartups and PerSourceNetBlockSize directives that provide more fine-grained control on a per-origin address basis than the global MaxStartups limit. = Bugfixes * ssh(1): Prefix keyboard interactive prompts with "(user@host)" to make it easier to determine which connection they are associated with in cases like scp -3, ProxyJump, etc. bz#3224 * sshd(8): fix sshd_config SetEnv directives located inside Match blocks. GHPR201 * ssh(1): when requesting a FIDO token touch on stderr, inform the user once the touch has been recorded. * ssh(1): prevent integer overflow when ridiculously large ConnectTimeout values are specified, capping the effective value (for most platforms) at 24 days. bz#3229 * ssh(1): consider the ECDSA key subtype when ordering host key algorithms in the client. * ssh(1), sshd(8): rename the PubkeyAcceptedKeyTypes keyword to PubkeyAcceptedAlgorithms. The previous name incorrectly suggested that it control allowed key algorithms, when this option actually specifies the signature algorithms that are accepted. The previous name remains available as an alias. bz#3253 * ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms. * sftp-server(8): add missing lsetstat@openssh.com documentation and advertisement in the server's SSH2_FXP_VERSION hello packet. * ssh(1), sshd(8): more strictly enforce KEX state-machine by banning packet types once they are received. Fixes memleak caused by duplicate SSH2_MSG_KEX_DH_GEX_REQUEST (oss-fuzz #30078). * sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit platforms instead of being limited by LONG_MAX. bz#3206 * Minor man page fixes (capitalization, commas, etc.) bz#3223 * sftp(1): when doing an sftp recursive upload or download of a read-only directory, ensure that the directory is created with write and execute permissions in the interim so that the transfer can actually complete, then set the directory permission as the final step. bz#3222 * ssh-keygen(1): document the -Z, check the validity of its argument earlier and provide a better error message if it's not correct. bz#2879 * ssh(1): ignore comments at the end of config lines in ssh_config, similar to what we already do for sshd_config. bz#2320 * sshd_config(5): mention that DisableForwarding is valid in a sshd_config Match block. bz3239 * sftp(1): fix incorrect sorting of "ls -ltr" under some circumstances. bz3248. * ssh(1), sshd(8): fix potential integer truncation of (unlikely) timeout values. bz#3250 * ssh(1): make hostbased authentication send the signature algorithm in its SSH2_MSG_USERAUTH_REQUEST packets instead of the key type. This make HostbasedAcceptedAlgorithms do what it is supposed to - filter on signature algorithm and not key type. - Rebased patches: * openssh-7.7p1-IPv6_X_forwarding.patch * openssh-7.7p1-X11_trusted_forwarding.patch * openssh-7.7p1-X_forward_with_disabled_ipv6.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-disable_openssl_abi_check.patch * openssh-7.7p1-eal3.patch * openssh-7.7p1-enable_PAM_by_default.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-host_ident.patch * openssh-7.7p1-hostname_changes_when_forwarding_X.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-no_fork-no_pid_file.patch * openssh-7.7p1-pam_check_locks.patch * openssh-7.7p1-pts_names_formatting.patch * openssh-7.7p1-remove_xauth_cookies_on_exit.patch * openssh-7.7p1-seccomp_ipc_flock.patch * openssh-7.7p1-seccomp_stat.patch * openssh-7.7p1-send_locale.patch * openssh-7.7p1-sftp_force_permissions.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-7.7p1-systemd-notify.patch * openssh-7.9p1-keygen-preserve-perms.patch * openssh-7.9p1-revert-new-qos-defaults.patch * openssh-8.0p1-gssapi-keyex.patch * openssh-8.1p1-audit.patch * openssh-8.1p1-seccomp-clock_gettime64.patch * openssh-8.1p1-seccomp-clock_nanosleep.patch * openssh-8.1p1-seccomp-clock_nanosleep_time64.patch * openssh-8.1p1-use-openssl-kdf.patch * openssh-8.4p1-vendordir.patch * openssh-fips-ensure-approved-moduli.patch * openssh-link-with-sk.patch * openssh-reenable-dh-group14-sha1-default.patch * openssh-whitelist-syscalls.patch - Removed openssh-fix-ssh-copy-id.patch (fixed upstream). - openssh.keyring: rotated to new key from https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/RELEASE_KEY.asc- sshd-gen-keys-start: - only source sysconfig file if it exists. - create /etc/ssh if it does not exists. Required for image based installation/updates.- The linux kernel has close_range(2) syscall which current glibc uses to implement closefrom(3) which will be then used by openssh. whitelist the new system call so closefrom does not fail or fallback to iterating proc/self/fd (openssh-whitelist-syscalls.patch)- Don't move user-modified ssh_config and sshd_config files to .rpmsave on upgrade.- Add openssh-mitigate-lingering-secrets.patch (bsc#1186673), which attempts to mitigate instances of secrets lingering in memory after a session exits. (bsc#1213004 bsc#1213008)- Add openssh-7.6p1-audit_race_condition.patch, fixing sshd termination of multichannel sessions with non-root users (error on 'mm_request_receive_expect') (bsc#1115550, bsc#1174162).- Use pam_motd to unify motd message output [bsc#1185897] (openssh-8.4p1-pam_motd.patch)- Change vendor configuration dir from /usr/share/ssh/ to /usr/etc/ssh/. - Remove upgrade enablement hack. This has been fixed in systemd-rpm-macros (bsc#1180083).- Add support for vendor provided configuration files in /usr/share/ssh/ (openssh-8.4p1-vendordir.patch) - Move configuration files from /etc/ssh/ to /usr/share/ssh/- Drop openssh-7.7p1-allow_root_password_login.patch to prevent login as root via password by default (is also upstream default). Comment indicates that this was a temporary meassure that we now had for five years, time to get rid of it (bsc#1173067)- Add openssh-whitelist-syscalls.patch (bsc#1182232), fixing failure to accept connections on 32-bit platforms with glibc 2.33+.- Add support for /etc/ssh/ssh_config.d and /etc/ssh/sshd_config.d (openssh-8.4p1-ssh_config_d.patch)- Add openssh-fix-ssh-copy-id.patch, which fixes breakage introduced in 8.4p1 (bsc#1181311).- Improve robustness of sshd init detection when upgrading from a pre-systemd distribution.- Add openssh-reenable-dh-group14-sha1-default.patch, which adds diffie-hellman-group14-sha1 key exchange back to the default list (bsc#1180958). This is needed for backwards compatibility with older platforms.- Make sure sshd is enabled correctly when upgrading from a pre-systemd distribution (bsc#1180083).- sysusers-sshd.conf: use sysusers.d configuration file to create sshd user (avoid hard dependency on shadow).- update to 8.4p1: Security ======== * ssh-agent(1): restrict ssh-agent from signing web challenges for FIDO/U2F keys. * ssh-keygen(1): Enable FIDO 2.1 credProtect extension when generating a FIDO resident key. * ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for each use. These keys may be generated using ssh-keygen using a new "verify-required" option. When a PIN-required key is used, the user will be prompted for a PIN to complete the signature operation. New Features - ----------- * sshd(8): authorized_keys now supports a new "verify-required" option to require FIDO signatures assert that the token verified that the user was present before making the signature. The FIDO protocol supports multiple methods for user-verification, but currently OpenSSH only supports PIN verification. * sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn signatures. Webauthn is a standard for using FIDO keys in web browsers. These signatures are a slightly different format to plain FIDO signatures and thus require explicit support. * ssh(1): allow some keywords to expand shell-style ${ENV} environment variables. The supported keywords are CertificateFile, ControlPath, IdentityAgent and IdentityFile, plus LocalForward and RemoteForward when used for Unix domain socket paths. bz#3140 * ssh(1), ssh-agent(1): allow some additional control over the use of ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable, including forcibly enabling and disabling its use. bz#69 * ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time limit for keys in addition to its current flag options. Time- limited keys will automatically be removed from ssh-agent after their expiry time has passed. * scp(1), sftp(1): allow the -A flag to explicitly enable agent forwarding in scp and sftp. The default remains to not forward an agent, even when ssh_config enables it. * ssh(1): add a '%k' TOKEN that expands to the effective HostKey of the destination. This allows, e.g., keeping host keys in individual files using "UserKnownHostsFile ~/.ssh/known_hosts.d/%k". bz#1654 * ssh(1): add %-TOKEN, environment variable and tilde expansion to the UserKnownHostsFile directive, allowing the path to be completed by the configuration (e.g. bz#1654) * ssh-keygen(1): allow "ssh-add -d -" to read keys to be deleted from stdin. bz#3180 * sshd(8): improve logging for MaxStartups connection throttling. sshd will now log when it starts and stops throttling and periodically while in this state. bz#3055 Bugfixes - ------- * ssh(1), ssh-keygen(1): better support for multiple attached FIDO tokens. In cases where OpenSSH cannot unambiguously determine which token to direct a request to, the user is now required to select a token by touching it. In cases of operations that require a PIN to be verified, this avoids sending the wrong PIN to the wrong token and incrementing the token's PIN failure counter (tokens effectively erase their keys after too many PIN failures). * sshd(8): fix Include before Match in sshd_config; bz#3122 * ssh(1): close stdin/out/error when forking after authentication completes ("ssh -f ...") bz#3137 * ssh(1), sshd(8): limit the amount of channel input data buffered, avoiding peers that advertise large windows but are slow to read from causing high memory consumption. * ssh-agent(1): handle multiple requests sent in a single write() to the agent. * sshd(8): allow sshd_config longer than 256k * sshd(8): avoid spurious "Unable to load host key" message when sshd load a private key but no public counterpart * ssh(1): prefer the default hostkey algorithm list whenever we have a hostkey that matches its best-preference algorithm. * sshd(1): when ordering the hostkey algorithms to request from a server, prefer certificate types if the known_hosts files contain a key marked as a @cert-authority; bz#3157 * ssh(1): perform host key fingerprint comparisons for the "Are you sure you want to continue connecting (yes/no/[fingerprint])?" prompt with case sensitivity. * sshd(8): ensure that address/masklen mismatches in sshd_config yield fatal errors at daemon start time rather than later when they are evaluated. * ssh-keygen(1): ensure that certificate extensions are lexically sorted. Previously if the user specified a custom extension then the everything would be in order except the custom ones. bz#3198 * ssh(1): also compare username when checking for JumpHost loops. bz#3057 * ssh-keygen(1): preserve group/world read permission on known_hosts files across runs of "ssh-keygen -Rf /path". The old behaviour was to remove all rights for group/other. bz#3146 * ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen manual page and usage(). * sshd(8): explicitly construct path to ~/.ssh/rc rather than relying on it being relative to the current directory, so that it can still be found if the shell startup changes its directory. bz#3185 * sshd(8): when redirecting sshd's log output to a file, undo this redirection after the session child process is forked(). Fixes missing log messages when using this feature under some circumstances. * sshd(8): start ClientAliveInterval bookkeeping before first pass through select() loop; fixed theoretical case where busy sshd may ignore timeouts from client. * ssh(1): only reset the ServerAliveInterval check when we receive traffic from the server and ignore traffic from a port forwarding client, preventing a client from keeping a connection alive when it should be terminated. bz#2265 * ssh-keygen(1): avoid spurious error message when ssh-keygen creates files outside ~/.ssh * sftp-client(1): fix off-by-one error that caused sftp downloads to make one more concurrent request that desired. This prevented using sftp(1) in unpipelined request/response mode, which is useful when debugging. bz#3054 * ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect() helpers. bz#3071 * ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to write to it so we don't leave an empty .ssh directory when it's not needed. bz#3156 * ssh(1), sshd(8): fix multiplier when parsing time specifications when handling seconds after other units. bz#3171- Update openssh-8.1p1-audit.patch (bsc#1180501). This fixes occasional crashes on connection termination caused by accessing freed memory.- Support /usr/etc/pam.d- Fix build breakage caused by missing security key objects: + Modify openssh-7.7p1-cavstest-ctr.patch. + Modify openssh-7.7p1-cavstest-kdf.patch. + Add openssh-link-with-sk.patch.- Add openssh-fips-ensure-approved-moduli.patch (bsc#1177939). This ensures only approved DH parameters are used in FIPS mode.- Add openssh-8.1p1-ed25519-use-openssl-rng.patch (bsc#1173799). This uses OpenSSL's RAND_bytes() directly instead of the internal ChaCha20-based implementation to obtain random bytes for Ed25519 curve computations. This is required for FIPS compliance.- Work around %service_add_post disabling sshd on upgrade with package name change (bsc#1177039).- Fix fillup-template usage: + %post server needs to reference ssh (not sshd), which matches the sysconfig.ssh file name the package ships. + %post client does not need any fillup_ calls, as there is no client-relevant sysconfig file present. The naming of the sysconfig file (ssh instead of sshd) is unfortunate.- Use of DISABLE_RESTART_ON_UPDATE is deprecated. Replace it with %service_del_postun_without_restart- Move some Requires to the right subpackage. - Avoid ">&" bashism in %post. - Upgrade some old specfile constructs/macros and drop unnecessary %{?systemd_*}. - Trim descriptions and straighten out the grammar.- Split openssh package into openssh, openssh-common, openssh-server and openssh-clients. This allows for the ssh clients to be installed without the server component (bsc#1176434).- Version update to 8.3p1: = Potentially-incompatible changes * sftp(1): reject an argument of "-1" in the same way as ssh(1) and scp(1) do instead of accepting and silently ignoring it. = New features * sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore rhosts/shosts, "no" allow rhosts/shosts or (new) "shosts-only" to allow .shosts files but not .rhosts. * sshd(8): allow the IgnoreRhosts directive to appear anywhere in a sshd_config, not just before any Match blocks. * ssh(1): add %TOKEN percent expansion for the LocalFoward and RemoteForward keywords when used for Unix domain socket forwarding. * all: allow loading public keys from the unencrypted envelope of a private key file if no corresponding public key file is present. * ssh(1), sshd(8): prefer to use chacha20 from libcrypto where possible instead of the (slower) portable C implementation included in OpenSSH. * ssh-keygen(1): add ability to dump the contents of a binary key revocation list via "ssh-keygen -lQf /path". - Additional changes from 8.2p1 release: = Potentially-incompatible changes * ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa" (RSA/SHA1) algorithm from those accepted for certificate signatures (i.e. the client and server CASignatureAlgorithms option) and will use the rsa-sha2-512 signature algorithm by default when the ssh-keygen(1) CA signs new certificates. * ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1 from the default key exchange proposal for both the client and server. * ssh-keygen(1): the command-line options related to the generation and screening of safe prime numbers used by the diffie-hellman-group-exchange-* key exchange algorithms have changed. Most options have been folded under the -O flag. * sshd(8): the sshd listener process title visible to ps(1) has changed to include information about the number of connections that are currently attempting authentication and the limits configured by MaxStartups. * ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F support to provide address-space isolation for token middleware libraries (including the internal one). It needs to be installed in the expected path, typically under /usr/libexec or similar. = New features * This release adds support for FIDO/U2F hardware authenticators to OpenSSH. U2F/FIDO are open standards for inexpensive two-factor authentication hardware that are widely used for website authentication. In OpenSSH FIDO devices are supported by new public key types "ecdsa-sk" and "ed25519-sk", along with corresponding certificate types. * sshd(8): add an Include sshd_config keyword that allows including additional configuration files via glob(3) patterns. * ssh(1)/sshd(8): make the LE (low effort) DSCP code point available via the IPQoS directive. * ssh(1): when AddKeysToAgent=yes is set and the key contains no comment, add the key to the agent with the key's path as the comment. * ssh-keygen(1), ssh-agent(1): expose PKCS#11 key labels and X.509 subjects as key comments, rather than simply listing the PKCS#11 provider library path. * ssh-keygen(1): allow PEM export of DSA and ECDSA keys. * ssh(1), sshd(8): make zlib compile-time optional, available via the Makefile.inc ZLIB flag on OpenBSD or via the --with-zlib configure option for OpenSSH portable. * sshd(8): when clients get denied by MaxStartups, send a notification prior to the SSH2 protocol banner according to RFC4253 section 4.2. * ssh(1), ssh-agent(1): when invoking the $SSH_ASKPASS prompt program, pass a hint to the program to describe the type of desired prompt. The possible values are "confirm" (indicating that a yes/no confirmation dialog with no text entry should be shown), "none" (to indicate an informational message only), or blank for the original ssh-askpass behaviour of requesting a password/phrase. * ssh(1): allow forwarding a different agent socket to the path specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent option to accepting an explicit path or the name of an environment variable in addition to yes/no. * ssh-keygen(1): add a new signature operations "find-principals" to look up the principal associated with a signature from an allowed- signers file. * sshd(8): expose the number of currently-authenticating connections along with the MaxStartups limit in the process title visible to "ps". - Rebased patches: * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-no_fork-no_pid_file.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-8.0p1-gssapi-keyex.patch * openssh-8.1p1-audit.patch * openssh-8.1p1-seccomp-clock_nanosleep.patch - Removed openssh-7.7p1-seed-prng.patch (bsc#1165158).- add upstream signing key to actually verify source signature- Don't recommend xauth to avoid pulling in X.- Add patches to fix the sandbox blocking glibc on 32bit platforms (boo#1164061): * openssh-8.1p1-seccomp-clock_nanosleep_time64.patch * openssh-8.1p1-seccomp-clock_gettime64.patch- Add openssh-8.1p1-use-openssl-kdf.patch (jsc#SLE-9443). This performs key derivation using OpenSSL's SSHKDF facility, which allows OpenSSH to benefit from the former's FIPS certification status.- Make sure ssh-keygen runs if SSHD_AUTO_KEYGEN variable is unset or contains an unrecognized value (bsc#1157176).- Add openssh-8.1p1-seccomp-clock_nanosleep.patch, allow clock_nanosleep glibc master implements multiple functions using that syscall making the privsep sandbox kill the preauth process.- Update openssh-7.7p1-audit.patch to fix crash (bsc#1152730). Fix by Enzo Matsumiya (ematsumiya@suse.com). This was integrated in a separate code stream merged with the Oct. 10 update; the patch was also rebased and renamed to openssh-8.1p1-audit.patch.- Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574). This attempts to preserve the permissions of any existing known_hosts file when modified by ssh-keygen (for instance, with -R). - Added openssh-7.9p1-revert-new-qos-defaults.patch, which reverts an upstream commit that caused compatibility issues with other software (bsc#1136402).- Run 'ssh-keygen -A' on startup only if SSHD_AUTO_KEYGEN="yes" in /etc/sysconfig/ssh. This is set to "yes" by default, but can be changed by the system administrator (bsc#1139089).- Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574). This attempts to preserve the permissions of any existing known_hosts file when modified by ssh-keygen (for instance, with -R).- Version update to 8.1p1: * ssh-keygen(1): when acting as a CA and signing certificates with an RSA key, default to using the rsa-sha2-512 signature algorithm. Certificates signed by RSA keys will therefore be incompatible with OpenSSH versions prior to 7.2 unless the default is overridden (using "ssh-keygen -t ssh-rsa -s ..."). * ssh(1): Allow %n to be expanded in ProxyCommand strings * ssh(1), sshd(8): Allow prepending a list of algorithms to the default set by starting the list with the '^' character, E.g. "HostKeyAlgorithms ^ssh-ed25519" * ssh-keygen(1): add an experimental lightweight signature and verification ability. Signatures may be made using regular ssh keys held on disk or stored in a ssh-agent and verified against an authorized_keys-like list of allowed keys. Signatures embed a namespace that prevents confusion and attacks between different usage domains (e.g. files vs email). * ssh-keygen(1): print key comment when extracting public key from a private key. * ssh-keygen(1): accept the verbose flag when searching for host keys in known hosts (i.e. "ssh-keygen -vF host") to print the matching host's random-art signature too. * All: support PKCS8 as an optional format for storage of private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less insecure key derivation function than PEM's. - Additional changes from 8.0p1 release: * scp(1): Add "-T" flag to disable client-side filtering of server file list. * sshd(8): Remove support for obsolete "host/port" syntax. * ssh(1), ssh-agent(1), ssh-add(1): Add support for ECDSA keys in PKCS#11 tokens. * ssh(1), sshd(8): Add experimental quantum-computing resistant key exchange method, based on a combination of Streamlined NTRU Prime 4591^761 and X25519. * ssh-keygen(1): Increase the default RSA key size to 3072 bits, following NIST Special Publication 800-57's guidance for a 128-bit equivalent symmetric security level. * ssh(1): Allow "PKCS11Provider=none" to override later instances of the PKCS11Provider directive in ssh_config, * sshd(8): Add a log message for situations where a connection is dropped for attempting to run a command but a sshd_config ForceCommand=internal-sftp restriction is in effect. * ssh(1): When prompting whether to record a new host key, accept the key fingerprint as a synonym for "yes". This allows the user to paste a fingerprint obtained out of band at the prompt and have the client do the comparison for you. * ssh-keygen(1): When signing multiple certificates on a single command-line invocation, allow automatically incrementing the certificate serial number. * scp(1), sftp(1): Accept -J option as an alias to ProxyJump on the scp and sftp command-lines. * ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept "-v" command-line flags to increase the verbosity of output; pass verbose flags though to subprocesses, such as ssh-pkcs11-helper started from ssh-agent. * ssh-add(1): Add a "-T" option to allowing testing whether keys in an agent are usable by performing a signature and a verification. * sftp-server(8): Add a "lsetstat@openssh.com" protocol extension that replicates the functionality of the existing SSH2_FXP_SETSTAT operation but does not follow symlinks. * sftp(1): Add "-h" flag to chown/chgrp/chmod commands to request they do not follow symlinks. * sshd(8): Expose $SSH_CONNECTION in the PAM environment. This makes the connection 4-tuple available to PAM modules that wish to use it in decision-making. * sshd(8): Add a ssh_config "Match final" predicate Matches in same pass as "Match canonical" but doesn't require hostname canonicalisation be enabled. * sftp(1): Support a prefix of '@' to suppress echo of sftp batch commands. * ssh-keygen(1): When printing certificate contents using "ssh-keygen -Lf /path/certificate", include the algorithm that the CA used to sign the cert. - Rebased patches: * openssh-7.7p1-IPv6_X_forwarding.patch * openssh-7.7p1-X_forward_with_disabled_ipv6.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-disable_openssl_abi_check.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-hostname_changes_when_forwarding_X.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-seed-prng.patch * openssh-7.7p1-sftp_force_permissions.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-8.0p1-gssapi-keyex.patch (formerly openssh-7.7p1-gssapi_key_exchange.patch) * openssh-8.1p1-audit.patch (formerly openssh-7.7p1-audit.patch) - Removed patches (integrated upstream): * 0001-upstream-Fix-two-race-conditions-in-sshd-relating-to.patch * openssh-7.7p1-seccomp_ioctl_s390_EP11.patch * openssh-7.9p1-CVE-2018-20685.patch * openssh-7.9p1-brace-expansion.patch * openssh-CVE-2019-6109-force-progressmeter-update.patch * openssh-CVE-2019-6109-sanitize-scp-filenames.patch * openssh-CVE-2019-6111-scp-client-wildcard.patch - Removed patches (obsolete): * openssh-openssl-1_0_0-compatibility.patch- don't install SuSEfirewall2 service on Factory, since SuSEfirewall2 has been replaced by firewalld, see [1]. [1]: https://lists.opensuse.org/opensuse-factory/2019-01/msg00490.html- ssh-askpass: Try a fallback if the other option is not available- Fix a crash with GSSAPI key exchange (bsc#1136104) * modify openssh-7.7p1-gssapi_key_exchange.patch- Fix a double free() in the KDF CAVS testing tool (bsc#1065237) * modify openssh-7.7p1-cavstest-kdf.patch- Minor clean-up of the fips patches, modified openssh-7.7p1-fips.patch openssh-7.7p1-fips_checks.patch- Fix two race conditions in sshd relating to SIGHUP (bsc#1119183) * 0001-upstream-Fix-two-race-conditions-in-sshd-relating-to.patch- Correctly filter out non-compliant algorithms when in FIPS mode (bsc#1126397) * A hunk was applied to a wrong place due to a patch fuzz when the fips patch was being ported to openssh 7.9p1 - update openssh-7.7p1-fips.patch- Remove the "KexDHMin" config keyword (bsc#1127180) It used to allow lowering of the minimal allowed DH group size, which was increased to 2048 by upstream in the light of the Logjam attack. The code was broken since the upgrade to 7.6p1, but nobody noticed. As apparently no one needs the functionality any more, let's drop the patch. It's still possible to use the fixed 1024-bit diffie-hellman-group1-sha1 key exchange method when working with legacy systems. - drop openssh-7.7p1-disable_short_DH_parameters.patch - updated patches: openssh-7.7p1-fips.patch openssh-7.7p1-fips_checks.patch openssh-7.7p1-gssapi_key_exchange.patch- Handle brace expansion in scp when checking that filenames sent by the server side match what the client requested [bsc#1125687] * openssh-7.9p1-brace-expansion.patch- Updated security fixes: * [bsc#1121816, CVE-2019-6109] Sanitize scp filenames via snmprintf and have progressmeter force an update at the beginning and end of each transfer. Added patches: - openssh-CVE-2019-6109-sanitize-scp-filenames.patch - openssh-CVE-2019-6109-force-progressmeter-update.patch * [bsc#1121821, CVE-2019-6111] Check in scp client that filenames sent during remote->local directory copies satisfy the wildcard specified by the user. Added patch: - openssh-CVE-2019-6111-scp-client-wildcard.patch * Removed openssh-7.9p1-scp-name-validator.patch- Change the askpass wrapper to not use x11 interface: * by default we use the -gnome UI (which is gtk3 only, no gnome dep) * if desktop is KDE/LxQt we use ksshaskpass- Remove old conditionals- Move ssh-ldap* man pages into openssh-helpers [bsc#1051531]- Allow root login by default [bsc#1118114, bsc#1121196] * Added/updated previous patch openssh-7.7p1-allow_root_password_login.patch * Mention the change in README.SUSE- Added SLE conditionals in the spec files: * Keep gtk2-devel in openssh-askpass-gnome in SLE * Keep krb5-mini-devel in SLE - Removed obsolete configure options: * SSH protocol 1 --with-ssh1 * Smart card --with-opensc - Cleaned spec file with spec-cleaner- Security fix: * [bsc#1121816, CVE-2019-6109] scp client spoofing via object name * [bsc#1121818, CVE-2019-6110] scp client spoofing via stderr * [bsc#1121821, CVE-2019-6111] scp client missing received object name validation * Added patch openssh-7.9p1-scp-name-validator.patch- Security fix: [bsc#1121571, CVE-2018-20685] * The scp client allows remote SSH servers to bypass intended access restrictions * Added patch openssh-7.9p1-CVE-2018-20685.patch- Added compatibility with SuSEfirewall2 [bsc#1118044]- Update the firewall rules in Tumbleweed- Fix build with openssl < 1.1.0 * add openssh-openssl-1_0_0-compatibility.patch- openssh-7.7p1-audit.patch: fix sshd fatal error in mm_answer_keyverify: buffer error: incomplete message [bnc#1114008]- Version update to 7.9p1 * ssh(1), sshd(8): the setting of the new CASignatureAlgorithms option (see below) bans the use of DSA keys as certificate authorities. * sshd(8): the authentication success/failure log message has changed format slightly. It now includes the certificate fingerprint (previously it included only key ID and CA key fingerprint). * ssh(1), sshd(8): allow most port numbers to be specified using service names from getservbyname(3) (typically /etc/services). * sshd(8): support signalling sessions via the SSH protocol. A limited subset of signals is supported and only for login or command sessions (i.e. not subsystems) that were not subject to a forced command via authorized_keys or sshd_config. bz#1424 * ssh(1): support "ssh -Q sig" to list supported signature options. Also "ssh -Q help" to show the full set of supported queries. * ssh(1), sshd(8): add a CASignatureAlgorithms option for the client and server configs to allow control over which signature formats are allowed for CAs to sign certificates. For example, this allows banning CAs that sign certificates using the RSA-SHA1 signature algorithm. * sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to revoke keys specified by SHA256 hash. * ssh-keygen(1): allow creation of key revocation lists directly from base64-encoded SHA256 fingerprints. This supports revoking keys using only the information contained in sshd(8) authentication log messages. - Removed obsolete configuration option --with-tcp-wrappers, and - -with-opensc for s390 and s390x. - Removed patch merged upstream * openssh-7.7p1-openssl_1.1.0.patch - Refreshed patches * openssh-7.7p1-audit.patch * openssh-7.7p1-disable_short_DH_parameters.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-gssapi_key_exchange.patch * openssh-7.7p1-seccomp_ipc_flock.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-ldap.patch- Mention upstream bugs on multiple local patches - Adjust service to not spam restart and reload only on fails- Update openssh-7.7p1-sftp_force_permissions.patch from the upstream bug, and mention the bug in the spec- Drop patch openssh-7.7p1-allow_root_password_login.patch * There is no reason to set less secure default value, if users need the behaviour they can still set it up themselves - Drop patch openssh-7.7p1-blocksigalrm.patch * We had a bug way in past about this but it was never reproduced or even confirmed in the ticket, thus rather drop the patch- Disable ssh1 protocol support as neither RH or Debian enable this protocol by default anymore either.- Remove the mention of the SLE12 in the README.SUSE - Install firewall rules only when really needed ( ::1) before they are matched against known_hosts. bz#2763 * ssh(1): Don't accept junk after "yes" or "no" responses to hostkey prompts. bz#2803 * sftp(1): Have sftp print a warning about shell cleanliness when decoding the first packet fails, which is usually caused by shells polluting stdout of non-interactive startups. bz#2800 * ssh(1)/sshd(8): Switch timers in packet code from using wall-clock time to monotonic time, allowing the packet layer to better function over a clock step and avoiding possible integer overflows during steps. * Numerous manual page fixes and improvements.- Use TIRPC on suse_version >= 1500: sunrpc is deprecated and should be replaced by TIRPC.- additional rebased patches (bsc#1080779) * auditing support * LDAP integration * various distribution tweaks from SLE12 (X forwarding over IPv6, sftp forced permissions and verbose batch mode)- Use %license instead of %doc [bsc#1082318]- add OpenSSL 1.0 to 1.1 shim to remove dependency on old OpenSSL (update tracker: bsc#1080779)- Add missing crypto hardware enablement patches for IBM mainframes (FATE#323902)- add missing part of systemd integration (unit type)- BuildRequire pkgconfig(libsystemd) instead of systemd-devel: allow the scheduler to pick systemd-mini flavors to get build going.- Replace forgotten references to /var/adm/fillup-templates with new %_fillupdir macro (boo#1069468) - tighten configuration access rights- Update to vanilla 7.6p1 Most important changes (more details below): * complete removal of the ancient SSHv1 protocol * sshd(8) cannot run without privilege separation * removal of suport for arcfourm blowfish and CAST ciphers and RIPE-MD160 HMAC * refuse RSA keys shorter than 1024 bits Distilled upstream log: - OpenSSH 7.3 - --- Security * sshd(8): Mitigate a potential denial-of-service attack against the system's crypt(3) function via sshd(8). An attacker could send very long passwords that would cause excessive CPU use in crypt(3). sshd(8) now refuses to accept password authentication requests of length greater than 1024 characters. Independently reported by Tomas Kuthan (Oracle), Andres Rojas and Javier Nieto. * sshd(8): Mitigate timing differences in password authentication that could be used to discern valid from invalid account names when long passwords were sent and particular password hashing algorithms are in use on the server. CVE-2016-6210, reported by EddieEzra.Harari at verint.com * ssh(1), sshd(8): Fix observable timing weakness in the CBC padding oracle countermeasures. Reported by Jean Paul Degabriele, Kenny Paterson, Torben Hansen and Martin Albrecht. Note that CBC ciphers are disabled by default and only included for legacy compatibility. * ssh(1), sshd(8): Improve operation ordering of MAC verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms to verify the MAC before decrypting any ciphertext. This removes the possibility of timing differences leaking facts about the plaintext, though no such leakage has been observed. Reported by Jean Paul Degabriele, Kenny Paterson, Torben Hansen and Martin Albrecht. * sshd(8): (portable only) Ignore PAM environment vars when UseLogin=yes. If PAM is configured to read user-specified environment variables and UseLogin=yes in sshd_config, then a hostile local user may attack /bin/login via LD_PRELOAD or similar environment variables set via PAM. CVE-2015-8325, found by Shayan Sadigh. - --- New Features * ssh(1): Add a ProxyJump option and corresponding -J command-line flag to allow simplified indirection through a one or more SSH bastions or "jump hosts". * ssh(1): Add an IdentityAgent option to allow specifying specific agent sockets instead of accepting one from the environment. * ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be optionally overridden when using ssh -W. bz#2577 * ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per draft-sgtatham-secsh-iutf8-00. * ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K, 4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03. * ssh-keygen(1), ssh(1), sshd(8): support SHA256 and SHA512 RSA signatures in certificates; * ssh(1): Add an Include directive for ssh_config(5) files. * ssh(1): Permit UTF-8 characters in pre-authentication banners sent from the server. bz#2058 - --- Bugfixes * ssh(1), sshd(8): Reduce the syslog level of some relatively common protocol events from LOG_CRIT. bz#2585 * sshd(8): Refuse AuthenticationMethods="" in configurations and accept AuthenticationMethods=any for the default behaviour of not requiring multiple authentication. bz#2398 * sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!" message when forward and reverse DNS don't match. bz#2585 * ssh(1): Close ControlPersist background process stderr except in debug mode or when logging to syslog. bz#1988 * misc: Make PROTOCOL description for direct-streamlocal@openssh.com channel open messages match deployed code. bz#2529 * ssh(1): Deduplicate LocalForward and RemoteForward entries to fix failures when both ExitOnForwardFailure and hostname canonicalisation are enabled. bz#2562 * sshd(8): Remove fallback from moduli to obsolete "primes" file that was deprecated in 2001. bz#2559. * sshd_config(5): Correct description of UseDNS: it affects ssh hostname processing for authorized_keys, not known_hosts; bz#2554 * ssh(1): Fix authentication using lone certificate keys in an agent without corresponding private keys on the filesystem. bz#2550 * sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit is set; previously keepalive packets were not being sent. bz#2252 - --- Portability * ssh(1), sshd(8): Fix compilation by automatically disabling ciphers not supported by OpenSSL. bz#2466 * misc: Fix compilation failures on some versions of AIX's compiler related to the definition of the VA_COPY macro. bz#2589 * sshd(8): Whitelist more architectures to enable the seccomp-bpf sandbox. bz#2590 * ssh-agent(1), sftp-server(8): Disable process tracing on Solaris using setpflags(__PROC_PROTECT, ...). bz#2584 * sshd(8): On Solaris, don't call Solaris setproject() with UsePAM=yes it's PAM's responsibility. bz#2425 - OpenSSH 7.4 - --- Potentially-incompatible changes * ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit block ciphers are not safe in 2016 and we don't want to wait until attacks like SWEET32 are extended to SSH. As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the default configuration, but it's highly likely that such devices already need explicit configuration for key exchange and hostkey algorithms already anyway. * sshd(8): Remove support for pre-authentication compression. Doing compression early in the protocol probably seemed reasonable in the 1990s, but today it's clearly a bad idea in terms of both cryptography (cf. multiple compression oracle attacks in TLS) and attack surface. Pre-auth compression support has been disabled by default for >10 years. Support remains in the client. * ssh-agent will refuse to load PKCS#11 modules outside a whitelist of trusted paths by default. The path whitelist may be specified at run-time. * sshd(8): When a forced-command appears in both a certificate and an authorized keys/principals command= restriction, sshd will now refuse to accept the certificate unless they are identical. The previous (documented) behaviour of having the certificate forced-command override the other could be a bit confusing and error-prone. * sshd(8): Remove the UseLogin configuration directive and support for having /bin/login manage login sessions. - --- Security * ssh-agent(1): Will now refuse to load PKCS#11 modules from paths outside a trusted whitelist (run-time configurable). Requests to load modules could be passed via agent forwarding and an attacker could attempt to load a hostile PKCS#11 module across the forwarded agent channel: PKCS#11 modules are shared libraries, so this would result in code execution on the system running the ssh-agent if the attacker has control of the forwarded agent-socket (on the host running the sshd server) and the ability to write to the filesystem of the host running ssh-agent (usually the host running the ssh client). Reported by Jann Horn of Project Zero. * sshd(8): When privilege separation is disabled, forwarded Unix- domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. This release refuses Unix-domain socket forwarding when privilege separation is disabled (Privilege separation has been enabled by default for 14 years). Reported by Jann Horn of Project Zero. * sshd(8): Avoid theoretical leak of host private key material to privilege-separated child processes via realloc() when reading keys. No such leak was observed in practice for normal-sized keys, nor does a leak to the child processes directly expose key material to unprivileged users. Reported by Jann Horn of Project Zero. * sshd(8): The shared memory manager used by pre-authentication compression support had a bounds checks that could be elided by some optimising compilers. Additionally, this memory manager was incorrectly accessible when pre-authentication compression was disabled. This could potentially allow attacks against the privileged monitor process from the sandboxed privilege-separation process (a compromise of the latter would be required first). This release removes support for pre-authentication compression from sshd(8). Reported by Guido Vranken using the Stack unstable optimisation identification tool (http://css.csail.mit.edu/stack/) * sshd(8): Fix denial-of-service condition where an attacker who sends multiple KEXINIT messages may consume up to 128MB per connection. Reported by Shi Lei of Gear Team, Qihoo 360. * sshd(8): Validate address ranges for AllowUser and DenyUsers directives at configuration load time and refuse to accept invalid ones. It was previously possible to specify invalid CIDR address ranges (e.g. user@127.1.2.3/55) and these would always match, possibly resulting in granting access where it was not intended. Reported by Laurence Parry. - --- New Features * ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the version in PuTTY by Simon Tatham. This allows a multiplexing client to communicate with the master process using a subset of the SSH packet and channels protocol over a Unix-domain socket, with the main process acting as a proxy that translates channel IDs, etc. This allows multiplexing mode to run on systems that lack file- descriptor passing (used by current multiplexing code) and potentially, in conjunction with Unix-domain socket forwarding, with the client and multiplexing master process on different machines. Multiplexing proxy mode may be invoked using "ssh -O proxy ..." * sshd(8): Add a sshd_config DisableForwarding option that disables X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as anything else we might implement in the future. Like the 'restrict' authorized_keys flag, this is intended to be a simple and future-proof way of restricting an account. * sshd(8), ssh(1): Support the "curve25519-sha256" key exchange method. This is identical to the currently-supported method named "curve25519-sha256@libssh.org". * sshd(8): Improve handling of SIGHUP by checking to see if sshd is already daemonised at startup and skipping the call to daemon(3) if it is. This ensures that a SIGHUP restart of sshd(8) will retain the same process-ID as the initial execution. sshd(8) will also now unlink the PidFile prior to SIGHUP restart and re-create it after a successful restart, rather than leaving a stale file in the case of a configuration error. bz#2641 * sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives to appear in sshd_config Match blocks. * sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.) and a few more to provide access to the contents of the certificate being offered. * Added regression tests for string matching, address matching and string sanitisation functions. * Improved the key exchange fuzzer harness. - --- Bugfixes * ssh(1): Allow IdentityFile to successfully load and use certificates that have no corresponding bare public key. bz#2617 certificate id_rsa-cert.pub (and no id_rsa.pub). * ssh(1): Fix public key authentication when multiple authentication is in use and publickey is not just the first method attempted. bz#2642 * regress: Allow the PuTTY interop tests to run unattended. bz#2639 * ssh-agent(1), ssh(1): improve reporting when attempting to load keys from PKCS#11 tokens with fewer useless log messages and more detail in debug messages. bz#2610 * ssh(1): When tearing down ControlMaster connections, don't pollute stderr when LogLevel=quiet. * sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending sftp(1) to ensure that ssh(1) restores the terminal mode correctly if suspended during a password prompt. * ssh(1): Avoid busy-wait when ssh(1) is suspended during a password prompt. * ssh(1), sshd(8): Correctly report errors during sending of ext- info messages. * sshd(8): fix NULL-deref crash if sshd(8) received an out-of- sequence NEWKEYS message. * sshd(8): Correct list of supported signature algorithms sent in the server-sig-algs extension. bz#2547 * sshd(8): Fix sending ext_info message if privsep is disabled. * sshd(8): more strictly enforce the expected ordering of privilege separation monitor calls used for authentication and allow them only when their respective authentication methods are enabled in the configuration * sshd(8): Fix uninitialised optlen in getsockopt() call; harmless on Unix/BSD but potentially crashy on Cygwin. * Fix false positive reports caused by explicit_bzero(3) not being recognised as a memory initialiser when compiled with - fsanitize-memory. * sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for configuration examples. - --- Portability * On environments configured with Turkish locales, fall back to the C/POSIX locale to avoid errors in configuration parsing caused by that locale's unique handling of the letters 'i' and 'I'. bz#2643 * sftp-server(8), ssh-agent(1): Deny ptrace on OS X using ptrace(PT_DENY_ATTACH, ..) * ssh(1), sshd(8): Unbreak AES-CTR ciphers on old (~0.9.8) OpenSSL. * Fix compilation for libcrypto compiled without RIPEMD160 support. * contrib: Add a gnome-ssh-askpass3 with GTK+3 support. bz#2640 * sshd(8): Improve PRNG reseeding across privilege separation and force libcrypto to obtain a high-quality seed before chroot or sandboxing. * All: Explicitly test for broken strnvis. NetBSD added an strnvis and unfortunately made it incompatible with the existing one in OpenBSD and Linux's libbsd (the former having existed for over ten years). Try to detect this mess, and assume the only safe option if we're cross compiling. - OpenSSH 7.5 - --- Potentially-incompatible changes * This release deprecates the sshd_config UsePrivilegeSeparation option, thereby making privilege separation mandatory. Privilege separation has been on by default for almost 15 years and sandboxing has been on by default for almost the last five. * The format of several log messages emitted by the packet code has changed to include additional information about the user and their authentication state. Software that monitors ssh/sshd logs may need to account for these changes. For example: Connection closed by user x 1.1.1.1 port 1234 [preauth] Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth] Connection closed by invalid user x 1.1.1.1 port 1234 [preauth] Affected messages include connection closure, timeout, remote disconnection, negotiation failure and some other fatal messages generated by the packet code. * [Portable OpenSSH only] This version removes support for building against OpenSSL versions prior to 1.0.1. OpenSSL stopped supporting versions prior to 1.0.1 over 12 months ago (i.e. they no longer receive fixes for security bugs). - --- Security * ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed. Note that the OpenSSH client disables CBC ciphers by default, sshd offers them as lowest-preference options and will remove them by default entriely in the next release. Reported by Jean Paul Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen of Royal Holloway, University of London. * sftp-client(1): [portable OpenSSH only] On Cygwin, a client making a recursive file transfer could be maniuplated by a hostile server to perform a path-traversal attack. creating or modifying files outside of the intended target directory. Reported by Jann Horn of Google Project Zero. - --- New Features * ssh(1), sshd(8): Support "=-" syntax to easily remove methods from algorithm lists, e.g. Ciphers=-*cbc. bz#2671 - --- Bugfixes * sshd(1): Fix NULL dereference crash when key exchange start messages are sent out of sequence. * ssh(1), sshd(8): Allow form-feed characters to appear in configuration files. * sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs extension, where SHA2 RSA signature methods were not being correctly advertised. bz#2680 * ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in known_hosts processing. bz#2591 bz#2685 * ssh(1): Allow ssh to use certificates accompanied by a private key file but no corresponding plain *.pub public key. bz#2617 * ssh(1): When updating hostkeys using the UpdateHostKeys option, accept RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-* methods were enabled in HostkeyAlgorithms and not the old ssh-rsa method. bz#2650 * ssh(1): Detect and report excessively long configuration file lines. bz#2651 * Merge a number of fixes found by Coverity and reported via Redhat and FreeBSD. Includes fixes for some memory and file descriptor leaks in error paths. bz#2687 * ssh-keyscan(1): Correctly hash hosts with a port number. bz#2692 * ssh(1), sshd(8): When logging long messages to stderr, don't truncate "\r\n" if the length of the message exceeds the buffer. bz#2688 * ssh(1): Fully quote [host]:port in generated ProxyJump/-J command- line; avoid confusion over IPv6 addresses and shells that treat square bracket characters specially. * ssh-keygen(1): Fix corruption of known_hosts when running "ssh-keygen -H" on a known_hosts containing already-hashed entries. * Fix various fallout and sharp edges caused by removing SSH protocol 1 support from the server, including the server banner string being incorrectly terminated with only \n (instead of \r\n), confusing error messages from ssh-keyscan bz#2583 and a segfault in sshd if protocol v.1 was enabled for the client and sshd_config contained references to legacy keys bz#2686. * ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683 * sshd(8): Fix Unix domain socket forwarding for root (regression in OpenSSH 7.4). * sftp(1): Fix division by zero crash in "df" output when server returns zero total filesystem blocks/inodes. * ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors encountered during key loading to more meaningful error codes. bz#2522 bz#2523 * ssh-keygen(1): Sanitise escape sequences in key comments sent to printf but preserve valid UTF-8 when the locale supports it; bz#2520 * ssh(1), sshd(8): Return reason for port forwarding failures where feasible rather than always "administratively prohibited". bz#2674 * sshd(8): Fix deadlock when AuthorizedKeysCommand or AuthorizedPrincipalsCommand produces a lot of output and a key is matched early. bz#2655 * Regression tests: several reliability fixes. bz#2654 bz#2658 bz#2659 * ssh(1): Fix typo in ~C error message for bad port forward cancellation. bz#2672 * ssh(1): Show a useful error message when included config files can't be opened; bz#2653 * sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the manual page (previously incorrectly) advertised. bz#2637 * sshd_config(5): Repair accidentally-deleted mention of %k token in AuthorizedKeysCommand; bz#2656 * sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM; bz#2665 * ssh-agent(1): Relax PKCS#11 whitelist to include libexec and common 32-bit compatibility library directories. * sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME response handling. * ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys. It was not possible to delete them except by specifying their full physical path. bz#2682 - --- Portability * sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA crypto coprocessor. * sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg inspection. * ssh(1): Fix X11 forwarding on OSX where X11 was being started by launchd. bz#2341 * ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that contain non-printable characters where the codeset in use is ASCII. * build: Fix builds that attempt to link a kerberised libldns. bz#2603 * build: Fix compilation problems caused by unconditionally defining _XOPEN_SOURCE in wide character detection. * sshd(8): Fix sandbox violations for clock_gettime VSDO syscall fallback on some Linux/X32 kernels. bz#2142 - OpenSSH 7.6 - --- Potentially-incompatible changes This release includes a number of changes that may affect existing configurations: * ssh(1): delete SSH protocol version 1 support, associated configuration options and documentation. * ssh(1)/sshd(8): remove support for the hmac-ripemd160 MAC. * ssh(1)/sshd(8): remove support for the arcfour, blowfish and CAST ciphers. * Refuse RSA keys <1024 bits in length and improve reporting for keys that do not meet this requirement. * ssh(1): do not offer CBC ciphers by default. - --- Security * sftp-server(8): in read-only mode, sftp-server was incorrectly permitting creation of zero-length files. Reported by Michal Zalewski. - --- New Features * ssh(1): add RemoteCommand option to specify a command in the ssh config file instead of giving it on the client's command line. This allows the configuration file to specify the command that will be executed on the remote host. * sshd(8): add ExposeAuthInfo option that enables writing details of the authentication methods used (including public keys where applicable) to a file that is exposed via a $SSH_USER_AUTH environment variable in the subsequent session. * ssh(1): add support for reverse dynamic forwarding. In this mode, ssh will act as a SOCKS4/5 proxy and forward connections to destinations requested by the remote SOCKS client. This mode is requested using extended syntax for the - R and RemoteForward options and, because it is implemented solely at the client, does not require the server be updated to be supported. * sshd(8): allow LogLevel directive in sshd_config Match blocks; bz#2717 * ssh-keygen(1): allow inclusion of arbitrary string or flag certificate extensions and critical options. * ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as a CA when signing certificates. bz#2377 * ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit ToS/DSCP value and just use the operating system default. * ssh-add(1): added -q option to make ssh-add quiet on success. * ssh(1): expand the StrictHostKeyChecking option with two new settings. The first "accept-new" will automatically accept hitherto-unseen keys but will refuse connections for changed or invalid hostkeys. This is a safer subset of the current behaviour of StrictHostKeyChecking=no. The second setting "off", is a synonym for the current behaviour of StrictHostKeyChecking=no: accept new host keys, and continue connection for hosts with incorrect hostkeys. A future release will change the meaning of StrictHostKeyChecking=no to the behaviour of "accept-new". bz#2400 * ssh(1): add SyslogFacility option to ssh(1) matching the equivalent option in sshd(8). bz#2705 - --- Bugfixes * ssh(1): use HostKeyAlias if specified instead of hostname for matching host certificate principal names; bz#2728 * sftp(1): implement sorting for globbed ls; bz#2649 * ssh(1): add a user@host prefix to client's "Permission denied" messages, useful in particular when using "stacked" connections (e.g. ssh -J) where it's not clear which host is denying. bz#2720 * ssh(1): accept unknown EXT_INFO extension values that contain \0 characters. These are legal, but would previously cause fatal connection errors if received. * ssh(1)/sshd(8): repair compression statistics printed at connection exit * sftp(1): print '?' instead of incorrect link count (that the protocol doesn't provide) for remote listings. bz#2710 * ssh(1): return failure rather than fatal() for more cases during session multiplexing negotiations. Causes the session to fall back to a non-mux connection if they occur. bz#2707 * ssh(1): mention that the server may send debug messages to explain public key authentication problems under some circumstances; bz#2709 * Translate OpenSSL error codes to better report incorrect passphrase errors when loading private keys; bz#2699 * sshd(8): adjust compatibility patterns for WinSCP to correctly identify versions that implement only the legacy DH group exchange scheme. bz#2748 * ssh(1): print the "Killed by signal 1" message only at LogLevel verbose so that it is not shown at the default level; prevents it from appearing during ssh -J and equivalent ProxyCommand configs. bz#1906, bz#2744 * ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber existing keys if they exist but are zero length. zero-length keys could previously be made if ssh-keygen failed or was interrupted part way through generating them. bz#2561 * ssh(1): fix pledge(2) violation in the escape sequence "~&" used to place the current session in the background. * ssh-keyscan(1): avoid double-close() on file descriptors; bz#2734 * sshd(8): avoid reliance on shared use of pointers shared between monitor and child sshd processes. bz#2704 * sshd_config(8): document available AuthenticationMethods; bz#2453 * ssh(1): avoid truncation in some login prompts; bz#2768 * sshd(8): Fix various compilations failures, inc bz#2767 * ssh(1): make "--" before the hostname terminate argument processing after the hostname too. * ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting new-style private keys. Fixes problems related to private key handling for no-OpenSSL builds. bz#2754 * ssh(1): warn and do not attempt to use keys when the public and private halves do not match. bz#2737 * sftp(1): don't print verbose error message when ssh disconnects from under sftp. bz#2750 * sshd(8): fix keepalive scheduling problem: activity on a forwarded port from preventing the keepalive from being sent; bz#2756 * sshd(8): when started without root privileges, don't require the privilege separation user or path to exist. Makes running the regression tests easier without touching the filesystem. * Make integrity.sh regression tests more robust against timeouts. bz#2658 * ssh(1)/sshd(8): correctness fix for channels implementation: accept channel IDs greater than 0x7FFFFFFF. - --- Portability * sshd(9): drop two more privileges in the Solaris sandbox: PRIV_DAX_ACCESS and PRIV_SYS_IB_INFO; bz#2723 * sshd(8): expose list of completed authentication methods to PAM via the SSH_AUTH_INFO_0 PAM environment variable. bz#2408 * ssh(1)/sshd(8): fix several problems in the tun/tap forwarding code, mostly to do with host/network byte order confusion. bz#2735 * Add --with-cflags-after and --with-ldflags-after configure flags to allow setting CFLAGS/LDFLAGS after configure has completed. These are useful for setting sanitiser/fuzzing options that may interfere with configure's operation. * sshd(8): avoid Linux seccomp violations on ppc64le over the socketcall syscall. * Fix use of ldns when using ldns-config; bz#2697 * configure: set cache variables when cross-compiling. The cross- compiling fallback message was saying it assumed the test passed, but it wasn't actually set the cache variables and this would cause later tests to fail. * Add clang libFuzzer harnesses for public key parsing and signature verification. - packaging: * moving patches into a separate archive * first round of rebased patches: [-X11_trusted_forwarding] [-allow_root_password_login] [-blocksigalrm] [-cavstest-ctr] [-cavstest-kdf] [-disable_short_DH_parameters] [-eal3] [-enable_PAM_by_default] [-fips] [-fips_checks] [-gssapi_key_exchange] [-hostname_changes_when_forwarding_X] [-lastlog] [-missing_headers] [-pam_check_locks] [-pts_names_formatting] [-remove_xauth_cookies_on_exit] [-seccomp_geteuid] [-seccomp_getuid] [-seccomp_stat] [-seed-prng] [-send_locale] [-systemd-notify] * not rebased (obsoleted) patches (so far): [-additional_seccomp_archs] [-allow_DSS_by_default] [-default_protocol] [-dont_use_pthreads_in_PAM] [-eal3_obsolete] [-gssapimitm] [-saveargv-fix] * obviously removing all standalone patch files: [openssh-7.2p2-allow_root_password_login.patch] [openssh-7.2p2-allow_DSS_by_default.patch] [openssh-7.2p2-X11_trusted_forwarding.patch] [openssh-7.2p2-lastlog.patch] [openssh-7.2p2-enable_PAM_by_default.patch] [openssh-7.2p2-dont_use_pthreads_in_PAM.patch] [openssh-7.2p2-eal3.patch] [openssh-7.2p2-blocksigalrm.patch] [openssh-7.2p2-send_locale.patch] [openssh-7.2p2-hostname_changes_when_forwarding_X.patch] [openssh-7.2p2-remove_xauth_cookies_on_exit.patch] [openssh-7.2p2-pts_names_formatting.patch] [openssh-7.2p2-pam_check_locks.patch] [openssh-7.2p2-disable_short_DH_parameters.patch] [openssh-7.2p2-seccomp_getuid.patch] [openssh-7.2p2-seccomp_geteuid.patch] [openssh-7.2p2-seccomp_stat.patch] [openssh-7.2p2-additional_seccomp_archs.patch] [openssh-7.2p2-fips.patch] [openssh-7.2p2-cavstest-ctr.patch] [openssh-7.2p2-cavstest-kdf.patch] [openssh-7.2p2-seed-prng.patch] [openssh-7.2p2-gssapi_key_exchange.patch] [openssh-7.2p2-audit.patch] [openssh-7.2p2-audit_fixes.patch] [openssh-7.2p2-audit_seed_prng.patch] [openssh-7.2p2-login_options.patch] [openssh-7.2p2-disable_openssl_abi_check.patch] [openssh-7.2p2-no_fork-no_pid_file.patch] [openssh-7.2p2-host_ident.patch] [openssh-7.2p2-sftp_homechroot.patch] [openssh-7.2p2-sftp_force_permissions.patch] [openssh-7.2p2-X_forward_with_disabled_ipv6.patch] [openssh-7.2p2-ldap.patch] [openssh-7.2p2-IPv6_X_forwarding.patch] [openssh-7.2p2-ignore_PAM_with_UseLogin.patch] [openssh-7.2p2-prevent_timing_user_enumeration.patch] [openssh-7.2p2-limit_password_length.patch] [openssh-7.2p2-keep_slogin.patch] [openssh-7.2p2-kex_resource_depletion.patch] [openssh-7.2p2-verify_CIDR_address_ranges.patch] [openssh-7.2p2-restrict_pkcs11-modules.patch] [openssh-7.2p2-prevent_private_key_leakage.patch] [openssh-7.2p2-secure_unix_sockets_forwarding.patch] [openssh-7.2p2-ssh_case_insensitive_host_matching.patch] [openssh-7.2p2-disable_preauth_compression.patch] [openssh-7.2p2-s390_hw_crypto_syscalls.patch] [openssh-7.2p2-s390_OpenSSL-ibmpkcs11_syscalls.patch]- Replace references to /var/adm/fillup-templates with new %_fillupdir macro (boo#1069468)- sshd_config is has now permissions 0600 in secure mode- Fix preauth seccomp separation on mainframes (bsc#1016709) [openssh-7.2p2-s390_hw_crypto_syscalls.patch] [openssh-7.2p2-s390_OpenSSL-ibmpkcs11_syscalls.patch] - enable case-insensitive hostname matching (bsc#1017099) [openssh-7.2p2-ssh_case_insensitive_host_matching.patch] - add CAVS tests [openssh-7.2p2-cavstest-ctr.patch] [openssh-7.2p2-cavstest-kdf.patch] - Adding missing pieces for user matching (bsc#1021626) - Properly verify CIDR masks in configuration (bsc#1005893) [openssh-7.2p2-verify_CIDR_address_ranges.patch] - Remove pre-auth compression support from the server to prevent possible cryptographic attacks.

In particular, CBC ciphers and arcfour* are disabled by default. The full set of algorithms remains available if configured explicitly via the Ciphers and MACs sshd_config options. * sshd(8): Support for tcpwrappers/libwrap has been removed. * OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections using the curve25519-sha256@libssh.org KEX exchange method to fail when connecting with something that implements the specification correctly. OpenSSH 6.7 disables this KEX method when speaking to one of the affected versions. New Features: * ssh(1), sshd(8): Add support for Unix domain socket forwarding. A remote TCP port may be forwarded to a local Unix domain socket and vice versa or both ends may be a Unix domain socket. * ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519 key types. * sftp(1): Allow resumption of interrupted uploads. * ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is the same as the one sent during initial key exchange * sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses when GatewayPorts=no; allows client to choose address family * sshd(8): Add a sshd_config PermitUserRC option to control whether ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys option * ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that expands to a unique identifer based on a hash of the tuple of (local host, remote user, hostname, port). Helps avoid exceeding miserly pathname limits for Unix domain sockets in multiplexing control paths * sshd(8): Make the "Too many authentication failures" message include the user, source address, port and protocol in a format similar to the authentication success / failure messages Bugfixes: * sshd(8): Fix remote forwarding with the same listen port but different listen address. * ssh(1): Fix inverted test that caused PKCS#11 keys that were explicitly listed in ssh_config or on the commandline not to be preferred. * ssh-keygen(1): Fix bug in KRL generation: multiple consecutive revoked certificate serial number ranges could be serialised to an invalid format. Readers of a broken KRL caused by this bug will fail closed, so no should-have-been-revoked key will be accepted. * ssh(1): Reflect stdio-forward ("ssh -W host:port ...") failures in exit status. Previously we were always returning 0 * ssh(1), ssh-keygen(1): Make Ed25519 keys' title fit properly in the randomart border * ssh-agent(1): Only cleanup agent socket in the main agent process and not in any subprocesses it may have started (e.g. forked askpass). Fixes agent sockets being zapped when askpass processes fatal() * ssh-add(1): Make stdout line-buffered; saves partial output getting lost when ssh-add fatal()s part-way through (e.g. when listing keys from an agent that supports key types that ssh-add doesn't) * ssh-keygen(1): When hashing or removing hosts, don't choke on @revoked markers and don't remove @cert-authority markers * ssh(1): Don't fatal when hostname canonicalisation fails and a ProxyCommand is in use; continue and allow the ProxyCommand to connect anyway (e.g. to a host with a name outside the DNS behind a bastion) * scp(1): When copying local->remote fails during read, don't send uninitialised heap to the remote end. * sftp(1): Fix fatal "el_insertstr failed" errors when tab-completing filenames with a single quote char somewhere in the string * ssh-keyscan(1): Scan for Ed25519 keys by default. * ssh(1): When using VerifyHostKeyDNS with a DNSSEC resolver, down-convert any certificate keys to plain keys and attempt SSHFP resolution. Prevents a server from skipping SSHFP lookup and forcing a new-hostkey dialog by offering only certificate keys. - OpenSSH 6.8 Potentially-incompatible changes: * sshd(8): UseDNS now defaults to 'no'. Configurations that match against the client host name (via sshd_config or authorized_keys) may need to re-enable it or convert to matching against addresses. New Features: * Add FingerprintHash option to ssh(1) and sshd(8), and equivalent command-line flags to the other tools to control algorithm used for key fingerprints. The default changes from MD5 to SHA256 and format from hex to base64. Fingerprints now have the hash algorithm prepended. An example of the new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE Please note that visual host keys will also be different. * ssh(1), sshd(8): Experimental host key rotation support. Add a protocol extension for a server to inform a client of all its available host keys after authentication has completed. The client may record the keys in known_hosts, allowing it to upgrade to better host key algorithms and a server to gracefully rotate its keys. The client side of this is controlled by a UpdateHostkeys config option (default off). * ssh(1): Add a ssh_config HostbasedKeyType option to control which host public key types are tried during host-based authentication. * ssh(1), sshd(8): fix connection-killing host key mismatch errors when sshd offers multiple ECDSA keys of different lengths. * ssh(1): when host name canonicalisation is enabled, try to parse host names as addresses before looking them up for canonicalisation. fixes bz#2074 and avoiding needless DNS lookups in some cases. * ssh-keygen(1), sshd(8): Key Revocation Lists (KRLs) no longer require OpenSSH to be compiled with OpenSSL support. * ssh(1), ssh-keysign(8): Make ed25519 keys work for host based authentication. * sshd(8): SSH protocol v.1 workaround for the Meyer, et al, Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA decryption. * sshd(8): Remember which public keys have been used for authentication and refuse to accept previously-used keys. This allows AuthenticationMethods=publickey,publickey to require that users authenticate using two _different_ public keys. * sshd(8): add sshd_config HostbasedAcceptedKeyTypes and PubkeyAcceptedKeyTypes options to allow sshd to control what public key types will be accepted. Currently defaults to all. * sshd(8): Don't count partial authentication success as a failure against MaxAuthTries. * ssh(1): Add RevokedHostKeys option for the client to allow text-file or KRL-based revocation of host keys. * ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial number or key ID without scoping to a particular CA. * ssh(1): Add a "Match canonical" criteria that allows ssh_config Match blocks to trigger only in the second config pass. * ssh(1): Add a -G option to ssh that causes it to parse its configuration and dump the result to stdout, similar to "sshd -T". * ssh(1): Allow Match criteria to be negated. E.g. "Match !host". * The regression test suite has been extended to cover more OpenSSH features. The unit tests have been expanded and now cover key exchange. Bugfixes: * ssh-keyscan(1): ssh-keyscan has been made much more robust again servers that hang or violate the SSH protocol. * ssh(1), ssh-keygen(1): Fix regression: Key path names were being lost as comment fields. * ssh(1): Allow ssh_config Port options set in the second config parse phase to be applied (they were being ignored). * ssh(1): Tweak config re-parsing with host canonicalisation - make the second pass through the config files always run when host name canonicalisation is enabled (and not whenever the host name changes) * ssh(1): Fix passing of wildcard forward bind addresses when connection multiplexing is in use * ssh-keygen(1): Fix broken private key conversion from non-OpenSSH formats. * ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use. * Various fixes to manual pages - OpenSSH 6.9 Security: * ssh(1): when forwarding X11 connections with ForwardX11Trusted=no, connections made after ForwardX11Timeout expired could be permitted and no longer subject to XSECURITY restrictions because of an ineffective timeout check in ssh(1) coupled with "fail open" behaviour in the X11 server when clients attempted connections with expired credentials. This problem was reported by Jann Horn. * ssh-agent(1): fix weakness of agent locking (ssh-add -x) to password guessing by implementing an increasing failure delay, storing a salted hash of the password rather than the password itself and using a timing-safe comparison function for verifying unlock attempts. This problem was reported by Ryan Castellucci. New Features: * ssh(1), sshd(8): promote chacha20-poly1305@openssh.com to be the default cipher * sshd(8): support admin-specified arguments to AuthorizedKeysCommand * sshd(8): add AuthorizedPrincipalsCommand that allows retrieving authorized principals information from a subprocess rather than a file. * ssh(1), ssh-add(1): support PKCS#11 devices with external PIN entry devices * sshd(8): allow GSSAPI host credential check to be relaxed for multihomed hosts via GSSAPIStrictAcceptorCheck option * ssh-keygen(1): support "ssh-keygen -lF hostname" to search known_hosts and print key hashes rather than full keys. * ssh-agent(1): add -D flag to leave ssh-agent in foreground without enabling debug mode Bugfixes: * ssh(1), sshd(8): deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD message and do not try to use it against some 3rd-party SSH implementations that use it (older PuTTY, WinSCP). * Many fixes for problems caused by compile-time deactivation of SSH1 support (including bz#2369) * ssh(1), sshd(8): cap DH-GEX group size at 4Kbits for Cisco implementations as some would fail when attempting to use group sizes >4K * ssh(1): fix out-of-bound read in EscapeChar configuration option parsing * sshd(8): fix application of PermitTunnel, LoginGraceTime, AuthenticationMethods and StreamLocalBindMask options in Match blocks * ssh(1), sshd(8): improve disconnection message on TCP reset; bz#2257 * ssh(1): remove failed remote forwards established by muliplexing from the list of active forwards * sshd(8): make parsing of authorized_keys "environment=" options independent of PermitUserEnv being enabled * sshd(8): fix post-auth crash with permitopen=none * ssh(1), ssh-add(1), ssh-keygen(1): allow new-format private keys to be encrypted with AEAD ciphers * ssh(1): allow ListenAddress, Port and AddressFamily configuration options to appear in any order * sshd(8): check for and reject missing arguments for VersionAddendum and ForceCommand * ssh(1), sshd(8): don't treat unknown certificate extensions as fatal * ssh-keygen(1): make stdout and stderr output consistent * ssh(1): mention missing DISPLAY environment in debug log when X11 forwarding requested * sshd(8): correctly record login when UseLogin is set * sshd(8): Add some missing options to sshd -T output and fix output of VersionAddendum and HostCertificate. bz#2346 * Document and improve consistency of options that accept a "none" argument" TrustedUserCAKeys, RevokedKeys (bz#2382), AuthorizedPrincipalsFile (bz#2288) * ssh(1): include remote username in debug output * sshd(8): avoid compatibility problem with some versions of Tera Term, which would crash when they received the hostkeys notification message (hostkeys-00@openssh.com) * sshd(8): mention ssh-keygen -E as useful when comparing legacy MD5 host key fingerprints * ssh(1): clarify pseudo-terminal request behaviour and use make manual language consistent * ssh(1): document that the TERM environment variable is not subject to SendEnv and AcceptEnv - OpenSSH 7.0: This focuses primarily on deprecating weak, legacy and/or unsafe cryptography. Security: * sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world- writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev. * sshd(8): Portable OpenSSH only: Fixed a privilege separation weakness related to PAM support. Attackers who could successfully compromise the pre-authentication process for remote code execution and who had valid credentials on the host could impersonate other users. Reported by Moritz Jodeit. * sshd(8): Portable OpenSSH only: Fixed a use-after-free bug related to PAM support that was reachable by attackers who could compromise the pre-authentication process for remote code execution. Also reported by Moritz Jodeit. * sshd(8): fix circumvention of MaxAuthTries using keyboard- interactive authentication. By specifying a long, repeating keyboard-interactive "devices" string, an attacker could request the same authentication method be tried thousands of times in a single pass. The LoginGraceTime timeout in sshd(8) and any authentication failure delays implemented by the authentication mechanism itself were still applied. Found by Kingcope. Potentially-incompatible Changes: * Support for the legacy SSH version 1 protocol is disabled by default at compile time. * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is disabled by default at run-time. It may be re-enabled using the instructions in README.legacy or http://www.openssh.com/legacy.html * Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by default at run-time. These may be re-enabled using the instructions at http://www.openssh.com/legacy.html * Support for the legacy v00 cert format has been removed. * The default for the sshd_config(5) PermitRootLogin option has changed from "yes" to "prohibit-password". * PermitRootLogin=without-password/prohibit-password now bans all interactive authentication methods, allowing only public-key, hostbased and GSSAPI authentication (previously it permitted keyboard-interactive and password-less authentication if those were enabled). New Features: * ssh_config(5): add PubkeyAcceptedKeyTypes option to control which public key types are available for user authentication. * sshd_config(5): add HostKeyAlgorithms option to control which public key types are offered for host authentications. * ssh(1), sshd(8): extend Ciphers, MACs, KexAlgorithms, HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes options to allow appending to the default set of algorithms instead of replacing it. Options may now be prefixed with a '+' to append to the default, e.g. "HostKeyAlgorithms=+ssh-dss". * sshd_config(5): PermitRootLogin now accepts an argument of 'prohibit-password' as a less-ambiguous synonym of 'without- password'. Bugfixes: * ssh(1), sshd(8): add compatability workarounds for Cisco and more PuTTY versions. * Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux documentation relating to Unix domain socket forwarding * ssh(1): Improve the ssh(1) manual page to include a better description of Unix domain socket forwarding * ssh(1), ssh-agent(1): skip uninitialised PKCS#11 slots, fixing failures to load keys when they are present. * ssh(1), ssh-agent(1): do not ignore PKCS#11 hosted keys that wth empty CKA_ID * sshd(8): clarify documentation for UseDNS option - OpenSSH 7.1: Security: * sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas. Bugfixes: * ssh(1), sshd(8): add compatability workarounds for FuTTY * ssh(1), sshd(8): refine compatability workarounds for WinSCP * Fix a number of memory faults (double-free, free of uninitialised memory, etc) in ssh(1) and ssh-keygen(1). Reported by Mateusz Kocielski. - OpenSSH 7.1p2: * SECURITY: ssh(1): The OpenSSH client code between 5.4 and 7.1 contains experimential support for resuming SSH-connections (roaming). The matching server code has never been shipped, but the client code was enabled by default and could be tricked by a malicious server into leaking client memory to the server, including private client user keys. The authentication of the server host key prevents exploitation by a man-in-the-middle, so this information leak is restricted to connections to malicious or compromised servers. MITIGATION: For OpenSSH >= 5.4 the vulnerable code in the client can be completely disabled by adding 'UseRoaming no' to the gobal ssh_config(5) file, or to user configuration in ~/.ssh/config, or by passing -oUseRoaming=no on the command line. PATCH: See below for a patch to disable this feature (Disabling Roaming in the Source Code). This problem was reported by the Qualys Security Advisory team. * SECURITY: Eliminate the fallback from untrusted X11-forwarding to trusted forwarding for cases when the X server disables the SECURITY extension. Reported by Thomas Hoger. * SECURITY: Fix an out of-bound read access in the packet handling code. Reported by Ben Hawkes. * PROTOCOL: Correctly interpret the 'first_kex_follows' option during the intial key exchange. Reported by Matt Johnston. * Further use of explicit_bzero has been added in various buffer handling code paths to guard against compilers aggressively doing dead-store removal. Potentially-incompatible changes: * This release disables a number of legacy cryptographic algorithms by default in ssh: + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES. + MD5-based and truncated HMAC algorithms. - OpenSSH 7.2: Security: * ssh(1), sshd(8): remove unfinished and unused roaming code (was already forcibly disabled in OpenSSH 7.1p2). * ssh(1): eliminate fallback from untrusted X11 forwarding to trusted forwarding when the X server disables the SECURITY extension. * ssh(1), sshd(8): increase the minimum modulus size supported for diffie-hellman-group-exchange to 2048 bits. * sshd(8): pre-auth sandboxing is now enabled by default (previous releases enabled it for new installations via sshd_config). New Features: * all: add support for RSA signatures using SHA-256/512 hash algorithms based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt. * ssh(1): Add an AddKeysToAgent client option which can be set to 'yes', 'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a private key that is used during authentication will be added to ssh-agent if it is running (with confirmation enabled if set to 'confirm'). * sshd(8): add a new authorized_keys option "restrict" that includes all current and future key restrictions (no-*-forwarding, etc.). Also add permissive versions of the existing restrictions, e.g. "no-pty" -> "pty". This simplifies the task of setting up restricted keys and ensures they are maximally-restricted, regardless of any permissions we might implement in the future. * ssh(1): add ssh_config CertificateFile option to explicitly list certificates. bz#2436 * ssh-keygen(1): allow ssh-keygen to change the key comment for all supported formats. * ssh-keygen(1): allow fingerprinting from standard input, e.g. "ssh-keygen -lf -" * ssh-keygen(1): allow fingerprinting multiple public keys in a file, e.g. "ssh-keygen -lf ~/.ssh/authorized_keys" bz#1319 * sshd(8): support "none" as an argument for sshd_config Foreground and ChrootDirectory. Useful inside Match blocks to override a global default. bz#2486 * ssh-keygen(1): support multiple certificates (one per line) and reading from standard input (using "-f -") for "ssh-keygen -L" * ssh-keyscan(1): add "ssh-keyscan -c ..." flag to allow fetching certificates instead of plain keys. * ssh(1): better handle anchored FQDNs (e.g. 'cvs.openbsd.org') in hostname canonicalisation - treat them as already canonical and remove the trailing '.' before matching ssh_config. Bugfixes: * sftp(1): existing destination directories should not terminate recursive uploads (regression in openssh 6.8) * ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED replies to unexpected messages during key exchange. * ssh(1): refuse attempts to set ConnectionAttempts=0, which does not make sense and would cause ssh to print an uninitialised stack variable. * ssh(1): fix errors when attempting to connect to scoped IPv6 addresses with hostname canonicalisation enabled. * sshd_config(5): list a couple more options usable in Match blocks. * sshd(8): fix "PubkeyAcceptedKeyTypes +..." inside a Match block. * ssh(1): expand tilde characters in filenames passed to -i options before checking whether or not the identity file exists. Avoids confusion for cases where shell doesn't expand (e.g. "-i ~/file" vs. "-i~/file"). * ssh(1): do not prepend "exec" to the shell command run by "Match exec" in a config file, which could cause some commands to fail in certain environments. * ssh-keyscan(1): fix output for multiple hosts/addrs on one line when host hashing or a non standard port is in use * sshd(8): skip "Could not chdir to home directory" message when ChrootDirectory is active. * ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump. * sshd(8): avoid changing TunnelForwarding device flags if they are already what is needed; makes it possible to use tun/tap networking as non-root user if device permissions and interface flags are pre-established * ssh(1), sshd(8): RekeyLimits could be exceeded by one packet. * ssh(1): fix multiplexing master failure to notice client exit. * ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that present empty key IDs. * sshd(8): avoid printf of NULL argument. * ssh(1), sshd(8): allow RekeyLimits larger than 4GB. * ssh-keygen(1): sshd(8): fix several bugs in (unused) KRL signature support. * ssh(1), sshd(8): fix connections with peers that use the key exchange guess feature of the protocol. * sshd(8): include remote port number in log messages. * ssh(1): don't try to load SSHv1 private key when compiled without SSHv1 support. * ssh-agent(1), ssh(1): fix incorrect error messages during key loading and signing errors. * ssh-keygen(1): don't leave empty temporary files when performing known_hosts file edits when known_hosts doesn't exist. * sshd(8): correct packet format for tcpip-forward replies for requests that don't allocate a port * ssh(1), sshd(8): fix possible hang on closed output. * ssh(1): expand %i in ControlPath to UID. * ssh(1), sshd(8): fix return type of openssh_RSA_verify. * ssh(1), sshd(8): fix some option parsing memory leaks. * ssh(1): add a some debug output before DNS resolution; it's a place where ssh could previously silently stall in cases of unresponsive DNS servers. * ssh(1): remove spurious newline in visual hostkey. * ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+... * ssh(1): fix expansion of HostkeyAlgorithms=+... Documentation: * ssh_config(5), sshd_config(5): update default algorithm lists to match current reality. * ssh(1): mention -Q key-plain and -Q key-cert query options. * sshd_config(8): more clearly describe what AuthorizedKeysFile=none does. * ssh_config(5): better document ExitOnForwardFailure. * sshd(5): mention internal DH-GEX fallback groups in manual. * sshd_config(5): better description for MaxSessions option. Portability: * sshd(8): fix multiple authentication using S/Key. - OpenSSH 7.2p2: Security: * sshd(8): sanitise X11 authentication credentials to avoid xauth command injection when X11Forwarding is enabled.
