Description
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.

Remediation

Vendor Workaround

There is no complete mitigation for this vulnerability. As a risk-reduction measure, disable H.266/VVC media ingestion in GStreamer-based applications and media pipelines where that feature is not required. Until a fixed package is available, do not open or transcode H.266/VVC files or streams from untrusted sources.
