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

high Tenable Cloud Security Plugin ID 463688

Description

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

- A heap-buffer-overflow read vulnerability was found in libaom, the reference AV1 codec implementation. A
missing bounds check in the SVC (Scalable Video Coding) layer ID control function allows setting a
spatial_layer_id exceeding the configured number of layers. This causes an out-of-bounds heap read of
approximately 40,728 bytes when computing a layer context array index. An attacker who can influence SVC
encoder parameters in a network-facing service could exploit this for information disclosure (heap content
leak) or denial of service (segmentation fault from hitting unmapped memory). (CVE-2026-56210)

Solution

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