Description Dhananjay Arunesh 2021-04-19 02:58:26 UTC 
A division-by-zero exception was found in ImageMagick in MagickCore/gem.c. An attacker can submit a crafted file to ImageMagick and trigger the division-by-zero exception. It most likely will lead to a DoS attack, but could also cause other problems related to undefined behavior. This bug affects ImageMagick versions prior to 7.0.11-2.
