CVE-2020-27767: Debian Linux

Low severity, CVSS 3.3. EPSS: 1.1% chance of exploitation in the next 30 days.

A flaw was found in ImageMagick in MagickCore/quantum.h. 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 types `float` and `unsigned char`. 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

• Debian Debian Linux: version 9.0 only
• ImageMagick ImageMagick: before 6.9.10-69 (fixed in 6.9.10-69); from 7.0.0-0, before 7.0.9.0 (fixed in 7.0.9.0)
• Red Hat Enterprise Linux: version 5.0 only; version 6.0 only; version 7.0 only
