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).

Solution(s)

  • ffmpeg-upgrade-4_4_3
  • ffmpeg-upgrade-5_0_1
  • ffmpeg-upgrade-5_1_2
  • ffmpeg-upgrade-6_0
