Echo: cifs-utils: security update to 2:7.4-1+e1

high Tenable Self-Hosted Container Security Plugin ID 463130

Description

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

 - A flaw was found in the cifs-utils package where the cifs.upcall helper fails to securely drop its root
 privileges before looking up user information inside a user-controlled environment. A local, low
 privileged attacker can exploit this by using a crafted request_key payload to trick the root-owned helper
 into entering a custom environment (namespace) containing a malicious NSS module. This forces the system
 to load the attacker's controlled NSS Module and configuration, allowing them to execute arbitrary
 commands as the root user, elevating their privileges and fully compromising the system. (CVE-2026-12505)

Solution

Update the cifs-utils library and its related packages to version 2:7.4-1+e1 or later.
