AI-suggested
Red Hat has released an official security update that fixes this vulnerability in the gstreamer1-plugins-bad-free package. Users should apply the update to versions 10.2.4 or later to remediate the issue. For detailed update instructions, refer to Red Hat's advisory at https://access.redhat.com/articles/11258. No additional mitigation is required beyond applying the official patch.
Description
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.
