CVE-2020-27776: ImageMagick

Low severity, CVSS 3.3. EPSS: 0.9% chance of exploitation in the next 30 days.

A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.

Affected products

• ImageMagick ImageMagick: before 6.9.10-69 (fixed in 6.9.10-69); from 7.0.0-0, before 7.0.9 (fixed in 7.0.9)
• Red Hat Enterprise Linux: version 5.0 only; version 6.0 only; version 7.0 only
