## Overview

A flaw was found in ImageMagick. An attacker could exploit this issue by providing a specially crafted MAT image file that triggers an error-handling path where allocated memory is not properly released. Over time, repeated processing of these files can cause memory exhaustion, potentially leading to a Denial of Service (DoS).
