What is CVE-2020-27751?
CVE-2020-27751 is a low-severity vulnerability in Debian Debian Linux, published on 8 Dec 2020. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
A flaw was found in ImageMagick in MagickCore/quantum-export.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 long` as well as a shift exponent that is too large for 64-bit type. 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.
