In versions below both 7.1.2-19 and 6.9.13-44, the -sample operation has an out of bounds read when an specific offset is set through the `sample:offset` define that could lead to an out of bounds read. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19. ## Affected Packages 17 total 17 fixed Ecosystem Package Vulnerable range Fix .NETNuGet `Magick.NET-Q16-AnyCPU` all versions 14.12.0`dotnet add package Magick.NET-Q16-AnyCPU --version 14.12.0` .NETNuGet `Magick.NET-Q16-HDRI-AnyCPU` all versions 14.12.0`dotnet add package Magick.NET-Q16-HDRI-AnyCPU --version 14.12.0` .NETNuGet `Magick.NET-Q16-HDRI-OpenMP-arm64` all versions 14.12.0`dotnet add package Magick.NET-Q16-HDRI-OpenMP-arm64 --version 14.12.0` .NETNuGet `Magick.NET-Q16-HDRI-arm64` all versions 14.12.0`dotnet add package Magick.NET-Q16-HDRI-arm64 --version 14.12.0` .NETNuGet `Magick.NET-Q16-HDRI-x64` all versions 14.12.0`dotnet add package Magick.NET-Q16-HDRI-x64 --version 14.12.0` .NETNuGet `Magick.NET-Q16-HDRI-x86` all versions 14.12.0`dotnet add package Magick.NET-Q16-HDRI-x86 --version 14.12.0` ## Affected Products 1 product · 2 configurations Application `imagemagick`imagemagick ≥ 7.0.0-0 && < 7.1.2-19 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 14.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-33905 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.
