 Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix, which might result in denial of service, domain takeover, information disclosure or privilege escalation.

 For the stable distribution (trixie), these problems have been fixed in version 2:4.22.10+dfsg-0+deb13u2.

 We recommend that you upgrade your samba packages.

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