CVE-2020-27764  (opens in a new tab)
CWE-190  (opens in a new tab)

How to fix?

Upgrade ImageMagick/ImageMagick to version 6.9.10-69 or higher.

Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound. 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.
