References:
 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-6822
Description:
 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.
