CVE-2020-27764 (GCVE-0-2020-27764)

Vulnerability from cvelistv5 – Published: 2020-12-03 00:00 – Updated: 2024-08-04 16:18

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

Severity

No CVSS data available.
