medium Nessus Plugin ID 243419

Language:

Synopsis

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

Description

The version of libvpx installed on the remote host is prior to 1.9.0-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2960 advisory.

 VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding. (CVE-2023-44488)

 A heap overflow vulnerability exists in libvpx - Encoding a frame that has larger dimensions than the originally configured size with VP9 may result in a heap overflow in libvpx.We recommend upgrading to version 1.13.1 or above (CVE-2023-6349)

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 libvpx' to update your system.
