A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad. The gst av1 parser parse tile list obu() function passes a byte count to a bit-reader API that expects a bit count, causing parser desynchronization. A remote attacker could trick a user into opening a specially crafted AV1 media file, triggering an assertion abort and causing the application to crash.
