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.

A stack-based buffer overflow issue was found in pifs-utils. Parsing the mount.cifs ip command-line argument can lead to local attackers gaining root privileges. (CVE-2022-27239)

A flaw was found in cifs-utils. When verbose logging is enabled, invalid credentials file lines may be dumped to stderr. This may lead to information disclosure in particular conditions when the credentials file given is sensitive and contains = signs. (CVE-2022-29869)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
