Description Marian Rehak 2026-11-02 10:35:06 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.

FFmpeg 5.0 through 9.0.2 contains a path traversal vulnerability in the IMF demuxer that allows attackers to open files outside the package via unvalidated ASSETMAP Path elements. Attackers can supply a crafted IMF package with '..' or absolute paths to demux local MXF files, probe file existence and size, or trigger server-side requests.

Closing it as WONTFIX as i stopped updating chromium in EPEL8 because it started to require newer C++ standard that the aging system didn't support
