Name of the Vulnerable Software and Affected Versions
libaom (affected versions not specified)
Description
A heap buffer overflow occurs in the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing (LAP) mode allows the first-pass stats ring buffer wrap-around guard to be bypassed when the
g lag in frames variable is set to 1 or higher. This leads to a 232-byte out-of-bounds write on every encoded frame after the second, which corrupts adjacent heap objects. An attacker capable of influencing encoder configuration in a WebRTC session or transcoding service could cause a denial of service via a process crash or potentially achieve code execution.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
