LOWCVSS 3.3/10EPSS 1.15%

Last modified

CVE-2020-27764 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. 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. EPSS estimates a 1.15% chance of exploitation in the next 30 days.
