In ImageMagick, there is an outside the range of representable values of type 'unsigned long' at MagickCore/statistic.c. Reference: https://github.com/ImageMagick/ImageMagick/issues/1735
Acknowledgments: Name: Suhwan Song (Seoul National University)
Flaw summary: In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator() where a size_t cast should have been a ssize_t cast, which causes out-of-range values under some circumstances when a crafted input file is processed by ImageMagick. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was shown in this case.
