CWE-17  (opens in a new tab)

How to fix?

Upgrade Echo:latest ffmpeg to version 7:2.7.2-1 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 Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The destroy_buffers function in libavcodec/sanm.c in FFmpeg before 2.7.2 does not properly maintain height and width values in the video context, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via crafted LucasArts Smush video data.
