# CVE-2026-24485: ImageMagick: Infinite loop vulnerability when parsing a PCD file > Attackers can cause denial of service by providing a malformed PCD file that triggers an infinite loop in ImageMagick. - **Severity:** High 7.5 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 24 Feb 2026 - **Updated:** 26 Feb 2026 - **Also known as:** DEBIAN-CVE-2026-24485, ECHO-8502-3f7f-e2b6, GHSA-pqgj-2p96-rx85, JLSEC-2026-940, MINI-h2wj-cqw4-52fm, UBUNTU-CVE-2026-24485 ## What is CVE-2026-24485? CVE-2026-24485 is a high-severity denial of service vulnerability in Imagemagick Imagemagick, published on 24 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official 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, when a PCD file does not contain a valid Sync marker, the DecodeImage() function becomes trapped in an infinite loop while searching for the Sync marker, causing the program to become unresponsive and continuously consume CPU resources, ultimately leading to system resource exhaustion and denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch. Weakness: CWE-400 (Uncontrolled Resource Consumption) ## Which versions are affected by CVE-2026-24485? 38 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.
