Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-18 and 6.9.13-43, an out-of-bounds write of a zero byte exists in the X11 display interaction path that could lead to a crash. Versions 7.1.2-18 and 6.9.13-43 patch the issue.

Open-source dependencyDetect
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.
Fix
Update Magick.NET-Q16-AnyCPU to 14.11.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mw3m-pqr2-qv7c is resolved across your whole dependency graph.
Workarounds
Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
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.
Low impact. This flaw in ImageMagick's X11 display interaction path requires local access to trigger an out-of-bounds write, leading to a denial of service. Red Hat Enterprise Linux systems are affected if ImageMagick is installed and used in an X11 environment.
For systems where ImageMagick is not required, especially in server environments without a graphical interface, consider removing the `ImageMagick` package to eliminate the attack surface. This action may impact applications that rely on ImageMagick for image processing.Source: Red Hat security advisory for GHSA-mw3m-pqr2-qv7c (CC BY 4.0)
