Amazon Linux 2 : libarchive (ALAS-2023-2279)

critical Nessus Plugin ID 182637

Language:

Synopsis

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

Description

The version of libarchive installed on the remote host is prior to 3.1.2-14. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2279 advisory.

In libarchive 3.6.1, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference or, in some cases, even arbitrary code execution. (CVE-2022-36227)

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 libarchive' to update your system.
