    Package        : samba     Version        : 2:4.13.13+dfsg-1~deb11u8     CVE ID         : CVE-2026-2340 CVE-2026-3012 CVE-2026-3238 CVE-2026-4408                      CVE-2026-4480

    Several vulnerabilities have been discovered in Samba, a SMB/CIFS file,     print, and login server for Unix, which might result in bypass of access     checks, overwrite of files in unintended situations using the WORM vfs     module, installing CA certificates over http without verification when     auto-enrollment GPO is enabled, denial of service or remote code     execution.

    For Debian 11 bullseye, these problems have been fixed in version     2:4.13.13+dfsg-1~deb11u8.

    We recommend that you upgrade your samba packages.

    For the detailed security status of samba please refer to     its security tracker page at:
