## 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, the MSL interpreter crashes when processing a invalid `<map>` element that causes it to use an image after it has been freed. 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-2026-26983 is resolved across your whole dependency graph.
    
3.  ### Workarounds
    
    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
    

## 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

MODERATE: This flaw in ImageMagick allows a use-after-free vulnerability when processing a specially crafted MSL \`<map>\` element. An attacker could provide a malicious image file, leading to a denial of service due to application crashes. This affects systems where ImageMagick is used to process untrusted image files.

Workaround published by Red Hat

> To mitigate this issue, avoid processing untrusted or maliciously crafted image files with ImageMagick. If ImageMagick is used in a service, restrict access to trusted sources and ensure input validation is in place to prevent the processing of arbitrary or malformed MSL files.
