Description Andrej Nemec 2017-08-31 14:24:44 UTC

In ImageMagick before 6.9.9-3 and 7.x before 7.0.6-3, there is a missing NULL check in the ReadMATImage function in coders/mat.c, leading to a denial of service (assertion failure and application exit) in the DestroyImageInfo function in MagickCore/image.c.
