Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Magick.NET-Q16-AnyCPU, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update Magick.NET-Q16-AnyCPU to 14.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vf33-6r7x-66xx is resolved across your whole dependency graph.

  3. Workarounds

    Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatLow

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…

Workaround published by Red Hat
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.
