Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, in ReadSFWImage() (coders/sfw.c), when temporary file creation fails, read_info is destroyed before its filename member is accessed, causing a NULL pointer dereference and crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

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 14.10.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-25795 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
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.
This MODERATE impact flaw in ImageMagick can lead to a denial of service due to a NULL pointer dereference when processing a crafted SFW image file. The vulnerability occurs if temporary file creation fails during image processing. Red Hat Enterprise Linux 6 ELS and 7 ELS are affected by this flaw.
To reduce the risk associated with this vulnerability, avoid processing untrusted SFW image files with ImageMagick. If ImageMagick is deployed in environments where it processes untrusted input, consider implementing sandboxing or resource limits for ImageMagick processes to contain potential crashes and limit impact.Source: Red Hat security advisory for CVE-2026-25795 (CC BY 4.0)
