"The version of ImageMagick installed on the remote Windows host is 6.x
prior to 6.9.6-6. It is, therefore, affected by a denial of service
vulnerability due to an out-of-bounds read error in the ReadSGIImage()
function within file coders/sgi.c when handling iris info dimensions.
An unauthenticated, remote attacker can exploit this to crash a
process linked against the library or possibly disclose memory
contents.");
