Name of the Vulnerable Software and Affected Versions
libaom (affected versions not specified)
Description
A heap-buffer-overflow read occurs in the reference AV1 codec implementation due to a missing bounds check in the SVC (Scalable Video Coding) layer ID control function. This allows the
spatial layer id to be set beyond the configured number of layers, resulting in an out-of-bounds heap read of approximately 40,728 bytes during the computation of a layer context array index. An attacker capable of influencing SVC encoder parameters in a network-facing service could leverage this to cause a denial of service via a segmentation fault or achieve information disclosure through a heap content leak.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
