Language:

Synopsis

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

Description

The version of tar installed on the remote host is prior to 1.26-35. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2390 advisory.

It was discovered that tar incorrectly handled extended attributes in PAX archives. An attacker could supply a specially crafted file and cause tar to crash, resulting in a denial of service. (CVE-2023-39804)

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

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

Solution

Run 'yum update tar' to update your system.
