It was discovered that ImageMagick incorrectly handled certain JPEG
EXIF tags. If a user or automated system using ImageMagick were

Aleksis Kauppinen, Joonas Kuorilehto and Tuomas Parttimaa discovered
that ImageMagick incorrectly handled certain TIFF EXIF tags. If a user

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. (CVE-2012-1798).
