NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg-4-private-devel package and not the ffmpeg-4-private-devel package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

A use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash).
