NVD Description

Note: Versions mentioned in the description apply only to the upstream imagemagick package and not the imagemagick package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

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. This flaw affects ImageMagick versions prior to 6.9.10-69.
