Description Dhananjay Arunesh 2021-04-19 03:08:13 UTC 
A division-by-zero exception was found in ImageMagick in MagickCore/widget.c: XFileBrowserWidget(). It most likely will lead to a DoS attack affecting servers' availability, but could also cause other problems related to undefined behavior. This bug affects ImageMagick versions prior to 7.0.11-2 (included).
