NVD Description

Note: Versions mentioned in the description apply only to the upstream libMagickCore-7_Q16HDRI6 package and not the libMagickCore-7_Q16HDRI6 package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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.
