NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg-8.1-libswresample6 package and not the ffmpeg-8.1-libswresample6 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

FFmpeg before 8.1.3 contains a protection mechanism failure in the HLS demuxer that allows attackers to bypass protocol and allowed_extensions restrictions when opening child playlists. Attackers can supply a crafted master playlist whose child playlists use disallowed protocols or non-multimedia local files, making parse_playlist() open resources the HLS security policy should block.
