Echo: aom: security update to 3.12.1-1+e2

high Tenable Self-Hosted Container Security Plugin ID 460982

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw
 in the AV1 encoder's Look-Ahead Processing (LAP) mode causes the first-pass stats ring buffer wrap-around
 guard to be bypassed when g_lag_in_frames is set to 1 or higher. This results in a 232-byte out-of-bounds
 write on every encoded frame after the second, corrupting adjacent heap objects. An attacker who can
 influence encoder configuration in a transcoding service or WebRTC session could exploit this to cause a
 denial of service (process crash) or potentially achieve code execution. (CVE-2026-56208)

Solution

Update the aom library and its related packages to version 3.12.1-1+e2 or later.
