AI-suggested
Red Hat advises blocking untrusted H.264 RTP streams at the network perimeter using firewalls or UDP ingress filters to prevent malformed packets from reaching GStreamer pipelines. Alternatively, disabling or avoiding the use of the rtph264depay element when processing RTP from untrusted sources mitigates the risk. Red Hat products shipping gst-plugins-good versions below 1.28.0 are not affected. For affected versions, monitor vendor advisories for patches or updates.
Description
A vulnerability in GStreamer's gst-plugins-good H.264 RTP depayloader element allows remote attackers to trigger an out-of-bounds heap read by sending a malformed RTP packet. This flaw arises from a signed/unsigned integer conversion error when processing MTAP16 or MTAP24 multi-time aggregation RTP packets, causing a length counter underflow. Exploitation can crash the GStreamer pipeline (denial of service) and potentially expose adjacent heap memory in relay or transcoding scenarios.
