libaom: libaom: heap buffer overflow in AV1 encoder first-pass stats buffer via LAP mode

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 glaginframes is set to 1 or higher. This results in a 232-byte...
