FFmpeg before 2.8.12, 3.0.x and 3.1.x before 3.1.9, 3.2.x before 3.2.6, and 3.3.x before 3.3.2 does not properly restrict HTTP Live Streaming filename extensions and demuxer names, which allows attackers to read arbitrary files via crafted playlist data.

Security readout for executives and security teams

This flaw lets a malicious media playlist make vulnerable FFmpeg read files from the server running it. Business risk is highest where users can upload or submit media for automated processing, because sensitive local files could be exposed through that workflow. Internet-facing media upload, transcoding, preview, or ingestion services using affected FFmpeg or related Debian-packaged libav builds are the most plausible exposure points. Prioritize remediation for systems that process external media. Internal-only or non-media systems are lower priority, but stale FFmpeg packages should still be removed from production images. Mitigation focus: Inventory systems and containers that include FFmpeg or Debian libav packages.; Upgrade FFmpeg to a fixed branch version or later per vendor guidance.; Apply Debian DSA-3957 or DLA-1630-1 package updates where applicable..
