Description d'origine
La description telle que publiée par la source (souvent en anglais).
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.
