Summary

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.

Risk Assessment

An attacker can trick a victim into opening a malicious playlist, potentially leading to access to local files or services that should be blocked. This can compromise system confidentiality and integrity.

Recommendation

Update FFmpeg to version 8.1.3 or later. Additionally, do not open playlists from untrusted sources and enforce strict protocol restrictions.
