A flaw was found in FFmpeg. An infinite loop vulnerability in the HTTP Live Streaming (HLS) demuxer allows remote attackers to cause a Denial of Service (DoS). By tricking a user into processing a specially crafted, self-referencing playlist file, an attacker can force the application into an endless loop, resulting in excessive CPU consumption and causing the application to hang.

Description OSIDB Bzimport 2026-10-08 17:51:20 UTC
FFmpeg before 8.1.3 contains an infinite loop vulnerability in the HLS demuxer that allows remote attackers to cause denial of service because parse_playlist() accepts Master Playlist tags inside Media Playlists. Attackers can trick victims into opening a crafted self-referencing playlist that endlessly adds variants in hls_read_header(), causing unbounded CPU and I/O consumption.
