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