Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

GStreamer-SA-2026-0025: The MOV/MP4 demuxer (qtdemux) did not adequately validate row alignment against minimum stride requirements or width and height against chroma subsampling formats for uncompressed video carried in the uncC box. A crafted MOV/MP4 file can cause a crash or denial of service. Affects gst-plugins-good before 1.28.3; fixed in 1.28.3.
