Technical details

An integer overflow in the AV1 LEB128 variable-length integer parser (introduced in GStreamer 1.18) allows remote denial of service when processing malformed AV1 bitstreams. The vulnerability requires user interaction (opening/playing a file) and network-reachable attack vector, resulting in application crash with no data exposure or integrity impact.

Affected products

GStreamer GStreamer 1.18.0 through 1.28.1
