CVE-2016-10062

The ReadGROUP4Image function in coders/tiff.c in ImageMagick does not check the return value of the fwrite function, which allows remote attackers to cause a denial of service (application crash) via a crafted file.

This update removes the fix for CVE-2016-9773. ImageMagick-6 was not affected by CVE-2016-9773 and it caused a regression (at least in GraphicsMagick) (bsc#1017421).

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
