Hi, OpenSSH 9.4 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This is a bugfix release. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at http://www.openssh.com/portable.html#cvs At https://anongit.mindrot.org/openssh.git/ or via a mirror at Github: https://github.com/openssh/openssh-portable Running the regression tests supplied with Portable OpenSSH does not require installation and is a simply: $ ./configure && make tests Live testing on suitable non-production systems is also appreciated. Please send reports of success or failure to openssh-unix-dev at mindrot.org. Security bugs should be reported directly to openssh at openssh.com. Below is a summary of changes. More detail may be found in the ChangeLog in the portable OpenSSH tarballs. Thanks to the many people who contributed to this release. Changes since OpenSSH 9.3p2 ========================== This release fixes a number of bugs and adds some small features. 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 seperate ssh-pkcs11-helpers for each loaded provider. * ssh(1): make -f (fork after authentication) work correctly with multiplexed connections, including ControlPersist. bz3589 bz3589 * 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 Portability ----------- * All: a number of build fixes for various platforms and configuration combinations. * sshd(8): provide a replacement for the SELinux matchpathcon() function, which is deprecated. * All: relax libcrypto version checks for OpenSSL >=3. Beyond OpenSSL 3.0, the ABI compatibility guarantees are wider (only the library major must match instead of major and minor in earlier versions). bz#3548. * Tests: fix build problems for the sk-dummy.so FIDO provider module used in some tests. OpenSSH is brought to you by Markus Friedl, Niels Provos, Theo de Raadt, Kevin Steves, Damien Miller, Darren Tucker, Jason McIntyre, Tim Rice and Ben Lindstrom.
