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.
