Description

ImageMagick is free and open-source software used for editing and manipulating digital images. The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But, in versions prior to 7.1.2-13, the last element in the set is not properly initialized. This will result in a release of an invalid pointer inside DestroyBilateralTLS when the memory allocation fails. Version 7.1.2-13 contains a patch for the issue.

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-Q8-x64, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update Magick.NET-Q8-x64 to 14.10.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-22770 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 HatModerate

This vulnerability is rated Moderate for Red Hat products as it affects ImageMagick, a widely used image processing library. A flaw in the `BilateralBlurImage` method can lead to a release of an invalid pointer when memory allocation fails, potentially resulting in a denial of service. This issue impacts Red Hat…

Workaround published by Red Hat
To mitigate this issue, avoid processing untrusted image files with ImageMagick. If ImageMagick is used in an automated or server-side context, consider implementing sandboxing mechanisms to limit the impact of potential exploitation. Restricting the sources of images processed by ImageMagick to trusted origins can also reduce exposure.
