Echo: samba: security update to 2:4.22.10+dfsg-0+deb13u2

medium Tenable Cloud Security Plugin ID 461779

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in Samba's CTDB, the clustered database service used by Samba. Insufficient integrity
 validation of received CTDB protocol packets allows malformed packets containing invalid field lengths,
 improperly terminated strings, or inconsistent packet sizes to be processed without adequate bounds
 checking. A remote attacker with access to the CTDB private network may trigger a denial of service
 through process crashes or excessive memory consumption and, in limited cases, disclose adjacent memory
 contents. (CVE-2026-58224)

Solution

Update the samba library and its related packages to version 2:4.22.10+dfsg-0+deb13u2 or later.
