Description Guilherme de Almeida Suckevicz 2026-09-15 17:30:02 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.

A vulnerability was found in FFmpeg 8.0.x. This affects the function parse_playlist of the file libavformat/hlsproto.c of the component Duration Parser. Performing a manipulation of the argument duration/target_duration results in denial of service. The attack is possible to be carried out remotely. Upgrading to version 8.1 and 9.0 is able to mitigate this issue. The patch is named 64fafd63f0b4. Upgrading the affected component is recommended.

Comment 1 Guilherme de Almeida Suckevicz 2026-09-15 17:36:08 UTC

This issue affects FFmpeg versions 8.0.x. Fedora does not ship any affected version.

Closing this tracker as not a bug.
