Published: 3/29/2023Modified: 4/28/2026
Description
libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).
Affected packages (2)
- Debian/ffmpegfrom 0, < 7:4.3.7-0+deb11u1
