# CVE-2025-65955: ImageMagick has a use-after-free/double-free risk in Options::fontFamily when clearing family > Attackers can trigger a use-after-free in ImageMagick's font handling, causing crashes or potential code execution via crafted image processing. - **Severity:** Medium 4.9 (`CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 2 Dec 2025 - **Updated:** 23 Jun 2026 - **Also known as:** DEBIAN-CVE-2025-65955, GHSA-q3hc-j9x5-mp9m, MINI-rp3w-whxc-ccgg, OESA-2025-2791, OESA-2025-2792, OESA-2025-2793, OESA-2025-2833, OESA-2025-2834, OESA-2025-2835, openSUSE-SU-2025:15816-1 ## What is CVE-2025-65955? CVE-2025-65955 is a medium-severity use after free vulnerability in Imagemagick Imagemagick, published on 2 Dec 2025. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-9 and 6.9.13-34, there is a vulnerability in ImageMagick’s Magick++ layer that manifests when Options::fontFamily is invoked with an empty string. Clearing a font family calls RelinquishMagickMemory on _drawInfo->font, freeing the font string but leaving _drawInfo->font pointing to freed memory while _drawInfo->family is set to that (now-invalid) pointer. Any later cleanup or reuse of _drawInfo->font re-frees or dereferences dangling memory. DestroyDrawInfo and other setters (Options::font, Image::font) assume _drawInfo->font remains valid, so destruction or subsequent updates trigger crashes or heap corruption. This vulnerability is fixed in 7.1.2-9 and 6.9.13-34. Weakness: CWE-416 (Use After Free), CWE-415 (Double Free) ## Which versions are affected by CVE-2025-65955? 36 open source packages ship an affected version, including Magick.NET-Q16-AnyCPU, Magick.NET-Q16-HDRI-AnyCPU and Magick.NET-Q16-HDRI-OpenMP-arm64.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
