Prior to versions 7.1.2-15 and 6.9.13-40, a crafted SVG file can cause a denial of service. An off-by-one boundary check (`>` instead of `>=`) that allows bypass the guard and reach an undefined `(size_t)` cast. 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-2026-25989 is resolved across your whole dependency graph. 3. ### Workarounds Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service. ## 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 is a MODERATE impact flaw in ImageMagick that could lead to a denial of service when processing a specially crafted SVG file. Red Hat Enterprise Linux 6 ELS and 7 ELS, as well as Community Projects like Fedora and EPEL, include ImageMagick. Exploitation requires an attacker to provide a malicious SVG file to a… Workaround published by Red Hat > To mitigate this issue, avoid processing untrusted SVG files with ImageMagick. If ImageMagick is used in an automated or server-side context, consider implementing sandboxing mechanisms or restricting the input sources to trusted origins to limit exposure to specially crafted SVG files.
