In GammaImage() of /MagickCore/enhance.c, depending on the gamma value,
it’s possible to trigger a divide-by-zero condition when a crafted input
file is processed by ImageMagick. This could lead to an impact to
application availability. The patch uses the PerceptibleReciprocal() to
prevent the divide-by-zero from occurring. This flaw affects ImageMagick
versions prior to ImageMagick 7.0.8-68.
