Description

A flaw was found in GStreamer's gst-plugins-good, specifically in the H.264 RTP depayloader element. When processing MTAP16 or MTAP24 multi-time aggregation RTP packets, a signed/unsigned integer conversion error causes the remaining-length counter to underflow to a large positive value when the packet is truncated. This allows a remote, unauthenticated attacker to trigger an out-of-bounds heap read of up to approximately 64 KiB of process memory by sending a single malformed RTP packet. Successful exploitation can crash the receiving GStreamer pipeline (denial of service), and in relay or transcoding deployments where output is accessible to the attacker, may expose adjacent heap contents.
