Amazon Linux 2 : cifs-utils (ALAS-2023-1977)

high Nessus Plugin ID 172161

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of cifs-utils installed on the remote host is prior to 6.2-10. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1977 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

Run 'yum update cifs-utils' to update your system.
