"The remote Windows host has a version of ImageMagick installed that is
7.x prior to 7.0.2-0. It is, therefore, affected by a denial of
service vulnerability due to a flaw in the ReadSUNImage() function
in sun.c that is triggered during the handling of malformed SUN
images. An unauthenticated, remote attacker can exploit this, by
convincing a user to open a specially crafted SUN image, to crash
processes linked against the library, resulting in a denial of service
condition.");
