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 heap buffer over-read vulnerability exists in multiple raw image format handles. The vulnerability occurs when processing images with -extract dimensions larger than -size dimensions, causing out-of-bounds memory reads from a heap-allocated buffer. 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 CVE-2026-25576 is resolved across your whole dependency graph.

  3. Workarounds

    Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

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 MODERATE impact vulnerability in ImageMagick is due to a heap buffer over-read when processing images with -extract dimensions larger than -size dimensions. This flaw could lead to out-of-bounds memory reads from a heap-allocated buffer. Red Hat Enterprise Linux and Community Projects are affected if ImageMagick…

Workaround published by Red Hat
To mitigate this issue, avoid processing untrusted or malformed image files with ImageMagick. Users should exercise caution when handling images from untrusted sources.
