Gst-plugins-base: gst-plugins-bad: gst-plugins-base/gst-plugins-bad: integer overflow in av1 leb128 parser allows denial of service

Impact

GStreamer has an integer overflow vulnerability in the AV1 LEB128 parser, allowing a remote attacker to cause a denial of service by crafting a malformed AV1 bitstream. The vulnerability affects Red Hat Enterprise Linux 10 and 9. An attacker can cause integer overflow in the parser, resulting in incorrect length values being used during stream processing.

Original source 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.
