-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Format: 1.8 Date: Sat, 02 Sep 2023 21:02:53 +0100 Source: openssh Architecture: source Version: 1:9.4p1-1 Distribution: unstable Urgency: medium Maintainer: Debian OpenSSH Maintainers <debian-ssh@lists.debian.org> Changed-By: Colin Watson <cjwatson@debian.org> Closes: 59255 348741 1035623 Changes: openssh (1:9.4p1-1) unstable; urgency=medium . * New upstream release (https://www.openssh.com/releasenotes.html#9.4p1): - 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. - 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%. - 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 (closes: #348741). - 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. - sshd(8), ssh(1), ssh-keygen(1): remove vestigial 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. - 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. - 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. - 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 explicitly set to "none". - scp(1): when copying local->remote, check that the source file exists before opening an SFTP connection to the server (closes: #59255). - sshd(8): provide a replacement for the SELinux matchpathcon() function, which is deprecated. - All: relax libcrypto version checks for OpenSSL >=3 (closes: #1035623). Beyond OpenSSL 3.0, the ABI compatibility guarantees are wider (only the library major must match instead of major and minor in earlier versions). - ssh-copy-id(1): Special case OpenWrt instead of Dropbear (LP: #1966886).
