Description Vladimir Vasilev 2026-10-19 08:24:46 UTC
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.

An issue was discovered in GStreamer gst-plugins-good before 1.28.2. While parsing an MP4 file, the isomp4 plugin's qtdemux_parse_uuid function may read past the end of a heap-allocated buffer, allowing an attacker to disclose heap memory contents.
