This bug was fixed in the package openssh - 1:9.3p1-1ubuntu1 --------------- openssh (1:9.3p1-1ubuntu1) mantic; urgency=medium * Merge with Debian unstable (LP: #2025664). Remaining changes: - debian/rules: modify dh_installsystemd invocations for socket-activated sshd - debian/openssh-server.postinst: handle migration of sshd_config options to systemd socket options on upgrade. - debian/README.Debian: document systemd socket activation. - debian/patches/socket-activation-documentation.patch: Document in sshd_config(5) that ListenAddress and Port no longer work. - debian/openssh-server.templates: include debconf prompt explaining when migration cannot happen due to multiple ListenAddress values - debian/.gitignore: drop file - debian/openssh-server.postrm: remove systemd drop-ins for socket-activated sshd on purge - debian/openssh-server.ucf-md5sum: update for Ubuntu delta - debian/openssh-server.tmpfile,debian/systemd/ssh.service: Move /run/sshd creation out of the systemd unit to a tmpfile config so that sshd can be run manually if necessary without having to create this directory by hand. - debian/patches/systemd-socket-activation.patch: Fix sshd re-execution behavior when socket activation is used - debian/tests/systemd-socket-activation: Add autopkgtest for systemd socket activation functionality. - d/p/test-set-UsePAM-no-on-some-tests.patch: set UsePAM=no for some tests - Ensure smooth upgrade path from versions affected by LP: #2020474: + debian/openssh-server.postint: do not try to restart systemd units, and instead indicate that a reboot is required + debian/tests/systemd-socket-activation: Reboot the testbed before starting the test + debian/rules: Do not stop ssh.socket on upgrade openssh (1:9.3p1-1) unstable; urgency=medium * Debconf translations: - Romanian (thanks, Remus-Gabriel Chelu; closes: #1033178). * Properly fix date of 1:3.0.2p1-2 changelog entry (closes: #1034425). * New upstream release (https://www.openssh.com/releasenotes.html#9.3p1): - [CVE-2023-28531] 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 (closes: #1033166). - [SECURITY] 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. - ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when outputting SSHFP fingerprints to allow algorithm selection. - 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. - scp(1), sftp(1): fix progressmeter corruption on wide displays. - 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. - ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol compatibility code and simplify what's left. - Fix a number of low-impact Coverity static analysis findings. - 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. - ssh(1): ensure that there is a terminating newline when adding a new entry to known_hosts. - 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. * debian/README.Debian: Clarify that you need to restart ssh.socket after overriding its ListenStream= option (LP: #2020560). * debian/openssh-server.postinst: Use "sshd -G" to parse the server configuration file (closes: #959726). * Fix incorrect RRSET_FORCE_EDNS0 flags validation in SSHFP DNSSEC patch (thanks, Ben Hutchings; closes: #909022). * Always use the internal mkdtemp implementation, since it substitutes more randomness into the template string than glibc's version (closes: #1001186). -- Nick Rosbrook
