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

high Tenable Cloud Security Plugin ID 460832

Description

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

 - A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation.
 Insufficient bounds validation in the AV1 encoder's SVC (Scalable Video Coding) layer ID control allows an
 attacker to supply crafted video frame pixels that overlap with internal encoder layer context structures.
 In fork-based video processing services, an attacker can use this to hijack the cyclic refresh map
 pointer, brute-force the process base address via a crash oracle, and redirect control flow to achieve
 arbitrary command execution. Exploitation requires the target service to use libaom with SVC encoding
 enabled and accept attacker-supplied video frames. (CVE-2026-56211)

Solution

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