## Overview

A flaw was found in ImageMagick. An attacker could exploit this vulnerability to cause a Denial of Service (DoS) or potentially execute arbitrary code on 32-bit systems. By convincing a user or automated service to process a specially crafted image requiring convex-hull calculations, an attacker can trigger a heap-based buffer overflow. This memory corruption causes the application to crash, disrupting service availability.
