high Nessus Plugin ID 351690

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1778015406 advisory.

- In cifs-utils through 6.14, a stack-based buffer overflow when parsing the mount.cifs ip= command-line argument could lead to local attackers gaining root privileges. (CVE-2022-27239)

- cifs-utils through 6.14, with verbose logging, can cause an information leak when a file contains = (equal sign) characters but is not a valid credentials file. (CVE-2022-29869)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory CENTOS7:CLSA-2026:1778015406.
