CWE-476  (opens in a new tab)

How to fix?

Upgrade Alpine:3.12 ffmpeg to version 4.0.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

In FFmpeg 4.0.1, due to a missing check of a profile value before setting it, the ff_mpeg4_decode_picture_header function in libavcodec/mpeg4videodec.c may trigger a NULL pointer dereference while converting a crafted AVI file to MPEG4, leading to a denial of service.
