Echo: samba: security update to 2:4.22.8+dfsg-0+deb13u2

medium Tenable Self-Hosted Container Security Plugin ID 462080

Description

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

 - A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-
 enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install
 it into the local trust store without proper verification. An attacker with the ability to intercept or
 redirect network traffic could exploit this behavior to supply a malicious certificate authority
 certificate, potentially allowing interception or spoofing of trusted communications. (CVE-2026-3012)

Solution

Update the samba library and its related packages to version 2:4.22.8+dfsg-0+deb13u2 or later.
