The Ubuntu security team deemed this advisory irrelevant for Ubuntu:16.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream imagemagick package and not the imagemagick package as distributed by Ubuntu.
Heap-based buffer overflow in the IsPixelGray function in MagickCore/pixel-accessor.h in ImageMagick 7.0.3.8 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a crafted image file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9556.
