A buffer over-read vulnerability exists in GStreamer's H.264 video decoding implementation that affects Mozilla Firefox, Firefox ESR, Thunderbird, and SeaMonkey on Linux systems. Remote attackers can trigger a denial of service (application crash) or potentially execute arbitrary code by crafting malicious H.264 video data within an m4v file. With an EPSS score of 7.61% (92nd percentile) and patches available from vendors, this vulnerability represents a moderate exploitation risk despite its CVSS 6.8 rating, indicating real-world prioritization is warranted for affected Linux deployments.
