GStreamer gst-plugins-bad vulnerabilities

A flaw was found in the GStreamer JPEG 2000 decimator in gst-plugins-bad. Crafted JPEG 2000 media can cause integer overflows or division by zero during tile processing. An application that processes the malicious media may crash, resulting in a denial of service.

A flaw exists in GStreamer's gst-plugins-bad H.266/VVC parser. When processing a malformed H.266 media file or stream, an integer overflow while parsing profile, tier, and level fields can lead to a stack-based buffer overflow.

An out-of-bounds write vulnerability was found in GStreamer's H.266/VVC PPS picture partition parser. In the multi-slice-in-tile processing of gst_h266_parser_parse_picture_partition(), the loop iterates without checking that the slice index stays within bounds, leading to writes past three fixed-size arrays.
