Summary
ImageMagick before 7.1.2-22 contains a division by zero vulnerability in binomial kernel processing that allows attackers to cause denial of service. An attacker can supply a large binomial kernel value causing integer overflow, resulting in division by zero and application crash.
An attacker can crash the application and cause service unavailability by submitting a maliciously crafted image. This flaw in ImageMagick is rated as Low impact.
An attacker can trigger a denial of service by providing a specially crafted image that, when processed, causes an integer overflow and subsequent division by zero. This issue requires user interaction, as the vulnerable ImageMagick instance must process the malicious input.

Mitigation checklist
- To mitigate this vulnerability, avoid processing untrusted or unverified image files with ImageMagick. Implement robust input validation and sanitization for any image processing workflows that handle external content. Consider running ImageMagick within a sandboxed environment to further limit the impact of potential denial of service attacks.
