A flaw was found 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 attacker could cause an application to crash and may be able to execute code in the context of the affected application.
