libaom vulnerabilities

The libaom library (reference AV1 codec implementation) contains a remote code execution vulnerability. Insufficient bounds validation in the AV1 encoder's SVC layer ID control allows an attacker to supply crafted video frames that can overwrite encoder context structures.

A heap-buffer-overflow read vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC layer ID control function allows setting a spatial_layer_id exceeding the configured number of layers, causing an out-of-bounds heap read of approximately 40,728 bytes.

An arbitrary address write vulnerability in libaom, the reference AV1 codec implementation, allows an attacker to inject an arbitrary pointer into the cyclic refresh map field via a missing bounds check in the SVC layer ID control function. An attacker who can supply frames to a network-facing libaom encoder with SVC enabled could exploit this for denial of service or potential code execution.

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.
