A flaw was found in ImageMagick in versions before 7.0.11, where a division
by zero in sRGBTransformImage() in the MagickCore/colorspace.c may trigger
undefined behavior via a crafted image file that is submitted by an
attacker processed by an application using ImageMagick. The highest threat
from this vulnerability is to system availability.
