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

Among the 22 debian patches available in version 1:10.5p1-1 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.)

testing migrations

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.
