CVE-2020-27764
Low 3.3
In plain English
A low-severity integer overflow in ImageMagick. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.2% (higher than 67% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
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.
