CVE-2022-48434 Open this link in a new tabHow to fix?
There is no fixed version for Ubuntu:20.04 ffmpeg.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Ubuntu.
See How to fix? for Ubuntu:20.04 relevant fixed versions and status.
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).
