NVD Description

Note: Versions mentioned in the description apply only to the upstream libaom-devel-doc package and not the libaom-devel-doc package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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).
