critical Nessus Plugin ID 171832

Language:

Synopsis

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

Description

The version of clamav installed on the remote host is prior to 0.103.8-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1964 advisory.

 Possible remote code execution vulnerability in the ClamAV HFS+ file parser. The issue affects ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier. (CVE-2023-20032)

 A possible remote information leak vulnerability in the DMG file parser. The issue affects versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier. (CVE-2023-20052)

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 clamav' to update your system.
