Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a crafted SVG file containing an malicious element causes ImageMagick to attempt to allocate ~674 GB of memory, leading to an out-of-memory abort. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

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 14.10.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v7g2-m8c5-mf84 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

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 HatImportant

This issue is classified as High severity by Red Hat Product Security. A remote attacker can craft an SVG image that, when processed by ImageMagick, induces extremely large memory allocation requests, leading to process failure or termination. The attack complexity is low and does not require any privileges or user…

Workaround published by Red Hat
To mitigate this vulnerability, avoid processing untrusted or unverified SVG image files with ImageMagick. When ImageMagick must process SVG files from untrusted sources, consider running the application in a sandboxed environment to limit potential resource exhaustion impacts.
