Description
A flaw was found in GStreamer. An integer overflow vulnerability in the AV1 LEB128 variable-length integer parser allows a remote attacker to cause a crash in applications that process AV1 media content. By crafting a malformed AV1 bitstream containing an invalid LEB128-encoded value, an attacker can cause integer overflow in the parser, resulting in incorrect length values being used during stream processing, which can lead to a denial of service.
