What is CVE-2020-25675?

CVE-2020-25675 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

In the CropImage() and CropImageToTiles() routines of MagickCore/transform.c, rounding calculations performed on unconstrained pixel offsets was causing undefined behavior in the form of integer overflow and out-of-range values as reported by UndefinedBehaviorSanitizer. Such issues could cause a negative impact to application availability or other problems related to undefined behavior, in cases where ImageMagick processes untrusted input data. The upstream patch introduces functionality to constrain the pixel offsets and prevent these issues. This flaw affects ImageMagick versions prior to 7.0.9-0.

Weakness: CWE-190
