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 stack buffer overflow occurs when processing the an attribute in msl.c. A long value overflows a fixed-size stack buffer, leading to memory corruption. 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-2026-25968 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

A MODERATE impact stack buffer overflow flaw exists in ImageMagick. This vulnerability occurs when processing a specially crafted image file containing a long attribute value, leading to memory corruption, unpredictable behavior, or a denial of service. This affects ImageMagick as shipped in Red Hat Enterprise Linux,…

Workaround published by Red Hat
To reduce the risk associated with this vulnerability, avoid processing untrusted or maliciously crafted image files with ImageMagick. If ImageMagick is not required for system operations, consider removing packages that depend on it. Removing ImageMagick or its dependent packages may affect applications that rely on its image processing capabilities.
