8 security issues in forky high

There are 8 open security issues in forky.

8 important issues:

CVE-2026-106552: In sftp in OpenSSH before 10.6, a server can trigger directory traversal (causing files to be written to unintended locations) during a recursive copy operation.
CVE-2026-106553: In sshd in OpenSSH before 10.6, credentials can incorrectly persist after failure of a GSSAPIAuthentication authentication attempt.
CVE-2026-106555: In sshd in OpenSSH before 10.6, GSSAPIAuthentication authentication state can incorrectly be persisted across authentication attempts.
CVE-2026-106582: In sshd and ssh in OpenSSH before 10.6, an LZ77 dictionary coder can be used even though this is contraindicated by the arXiv 2609.07709 "Crossing the Streams" findings.
CVE-2026-106583: In ssh in OpenSSH before 10.6, a $ or \ character can occur in a command-line username, leading to injection.
CVE-2026-106585: In sshd and ssh in OpenSSH before 10.6, there is no check for whether the maximum packet length is exceeded during decompression of highly compressed data.
CVE-2026-106586: In sshd in OpenSSH before 10.6, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not, a different vulnerability than CVE-2026-73283.
CVE-2026-106587: In sshd in OpenSSH before 10.6, the value "none" for a configuration option is sometimes interpreted as a filename but was intended to mean that a feature is disabled.

debian/patches: 1 patch with invalid metadata, 7 patches to forward upstream high

Among the 22 debian patches available in version 1:10.6p1-1 of the package, we noticed the following issues:

1 patch with invalid metadata that ought to be fixed.
7 patches where the metadata indicates that the patch has not yet been forwarded upstream. You should either forward the patch upstream or update the metadata to document its real status.

12 security issues in bullseye high

There are 12 open security issues in bullseye.

4 important issues:

CVE-2026-55654: A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service.
CVE-2026-73281: In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the session-bind@openssh.com extension.
CVE-2026-73282: In ssh in OpenSSH before 10.5, a use-after-free for realloc data can occur if a certain pair of remote-forwarding operations are concurrent.
CVE-2026-73283: In sshd in OpenSSH before 10.5, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not.

8 issues postponed or untriaged:

CVE-2026-59995: (postponed; to be fixed through a stable update) sftp in OpenSSH before 10.4 does not properly constrain the location of downloaded files when "sftp server:/path ." is used with an attacker-controlled server.
CVE-2026-59996: (postponed; to be fixed through a stable update) scp in OpenSSH before 10.4 may place a file in the parent directory of an intended directory when the copy occurs between two remote destinations.
CVE-2026-59997: (postponed; to be fixed through a stable update) internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.
CVE-2026-59998: (postponed; to be fixed through a stable update) sshd in OpenSSH before 10.4 has an undocumented security-relevant behavior: GSSAPIStrictAcceptorCheck has no value if the server is in Windows Active Directory.
CVE-2026-59999: (postponed; to be fixed through a stable update) In sshd in OpenSSH before 10.4, DisableForwarding=yes was supposed to take precedence over PermitTunnel=yes, but did not.
CVE-2026-60000: (postponed; to be fixed through a stable update) sshd in OpenSSH before 10.4 allows remote attackers to cause a denial of service (resource consumption from excessive authentication attempts) because MaxAuthTries was mishandled for GSSAPIAuthentication.
CVE-2026-60001: (postponed; to be fixed through a stable update) sshd in OpenSSH before 10.4 does not always honor the minimum authentication delay.
CVE-2026-60002: (postponed; to be fixed through a stable update) ssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re-exchange. (This outcome occurs only on the client side.)

commit e4cf7cec3d9d5b9b6c373bcd7f9471daf3a388e2
Merge: 6d466ae7 fa688ee4
Author: Colin Watson <cjwatson@debian.org>
Date:   Sun Oct 11 14:52:17 2026 +0000

    Merge branch 'salsa-openssh-purge-test' into 'master'
    
    d/t/purge-keeps-config-with-counterpart: test for purge
    
    See merge request ssh-team/openssh!42

commit fa688ee4ab0245fc699dd93ee0a09d736ef069b4
Author: Colin Watson <cjwatson@debian.org>
Date:   Sun Oct 11 15:13:04 2026 +0100

    Add isolation-container restriction
    
    While we might be able to get away without this in some cases,
    installing openssh-server/openssh-server-gssapi may involve starting
    services, so let's not push it.

commit eb313123e4a4a08c1509ebedc2393a50a2c898d4
Author: Colin Watson <cjwatson@debian.org>
Date:   Sun Oct 11 15:12:28 2026 +0100

    debputy reformat

commit 6d466ae720594d1dd51b06d64f9d78f80af3f2b3
Author: Colin Watson <cjwatson@debian.org>
Date:   Sun Oct 11 14:39:51 2026 +0100

    Make xinetd autopkgtest listen on port 2222, not 22
    
    This may make it less likely to fail in CI.

commit 7ac18ce7f402af6c30c0afbb22293e25f37f8c23
Author: Colin Watson <cjwatson@debian.org>
Date:   Sun Oct 11 13:48:59 2026 +0100

    Try harder to restart xinetd in autopkgtest
    
    Just reloading it sometimes mysteriously fails in CI with "Job for
    xinetd.service canceled."  Do a full restart instead, and wait for it to
    come back up.

commit 24dcdf1aa5fafd20da139fc463ab1d11d32ce829
Author: Colin Watson <cjwatson@debian.org>
Date:   Sun Oct 11 09:57:47 2026 +0100

    Run regress and non-regress autopkgtests in parallel
    
    The `regress` test takes much longer than the others, so these can
    usefully be parallelized.

commit 0cca73818244c1018d93876bb485d83de3239806
Author: Andreas Hasenack <andreas.hasenack@canonical.com>
Date:   Thu Oct 8 20:26:19 2026 -0300

    d/t/purge-keeps-config-with-counterpart: test for purge
    
    Test to validate that switching to the openssh counterparts and then
    purging the removed packages keeps the configuration intact.

commit 63f7b864252a97b7de9d831811f90ee46a827588
Author: Colin Watson <cjwatson@debian.org>
Date:   Fri Oct 9 13:32:26 2026 +0100

    Retroactively add changelog for #1148188

commit fe6733945a79a6f4bfd155da6a191ab5be156987
Author: Colin Watson <cjwatson@debian.org>
Date:   Wed Oct 7 12:06:06 2026 +0100

    debian/tests/xinetd: Make failure logs more useful
    
    We stop ssh.service for this test, so its logs aren't especially useful.
    Show logs from xinetd.service instead.

commit fb99559aafd009a569df881a61203239c8f220a4
Author: Colin Watson <cjwatson@debian.org>

testing migrations

This package is part of the ongoing testing transition known as auto-upperlimit-openssh-common. Please avoid uploads unrelated to this transition, they would likely delay it and require supplementary work from the release managers. On the other hand, if your package has problems preventing it to migrate to testing, please fix them as soon as possible. You can probably find supplementary information in the debian-release archives or in the corresponding release.debian.org bug.
This package will soon be part of the auto-openssl transition. You might want to ensure that your package is ready for it. You can probably find supplementary information in the debian-release archives or in the corresponding release.debian.org bug.
