Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16, an integer overflow vulnerability exists in the SIXEL decoer. The vulnerability allows an attacker to perform an out of bounds via a specially crafted image. This vulnerability is fixed in 7.1.2-16.

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 14.10.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-28493 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 affects ImageMagick in Red Hat Enterprise Linux and Community Projects. An integer overflow in the SIXEL decoder can lead to an out-of-bounds write when processing a specially crafted image, potentially resulting in a denial of service or other undefined behavior.

Workaround published by Red Hat
To mitigate this issue, avoid processing untrusted SIXEL image files with ImageMagick. If ImageMagick must process untrusted content, consider running it within a sandboxed environment to limit potential impact.
