Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the MAP image decoder when processing crafted MAP files, potentially leading to crashes or unintended memory disclosure during image decoding. Versions 7.1.2-15 and 6.9.13-40 contain a patch. ## Affected Packages 19 total 19 fixed Ecosystem Package Vulnerable range Fix .NETNuGet `Magick.NET-Q16-AnyCPU` all versions 14.10.3`dotnet add package Magick.NET-Q16-AnyCPU --version 14.10.3` .NETNuGet `Magick.NET-Q16-HDRI-AnyCPU` all versions 14.10.3`dotnet add package Magick.NET-Q16-HDRI-AnyCPU --version 14.10.3` .NETNuGet `Magick.NET-Q16-HDRI-OpenMP-arm64` all versions 14.10.3`dotnet add package Magick.NET-Q16-HDRI-OpenMP-arm64 --version 14.10.3` .NETNuGet `Magick.NET-Q16-HDRI-OpenMP-x64` all versions 14.10.3`dotnet add package Magick.NET-Q16-HDRI-OpenMP-x64 --version 14.10.3` .NETNuGet `Magick.NET-Q16-HDRI-arm64` all versions 14.10.3`dotnet add package Magick.NET-Q16-HDRI-arm64 --version 14.10.3` .NETNuGet `Magick.NET-Q16-HDRI-x64` all versions 14.10.3`dotnet add package Magick.NET-Q16-HDRI-x64 --version 14.10.3` ## Affected Products 1 product · 2 configurations Application `imagemagick`imagemagick ≥ 7.0.0-0 && < 7.1.2-15 range ## 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-2026-25987 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's MAP image decoder can lead to crashes or unintended memory disclosure when processing specially crafted MAP files. Red Hat Enterprise Linux 6 ELS and 7 ELS are affected by this flaw. Workaround published by Red Hat > To mitigate this issue, avoid processing untrusted MAP image files with ImageMagick. Restrict the sources of MAP files to only trusted origins to prevent potential exploitation.
