DescriptionCVE.org

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-51 and 7.1.2-26, a missing depth check in the MVG decoder will result in a stack overflow when a crafted image is provided. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.

AnalysisAI

Stack overflow in ImageMagick's MVG decoder prior to versions 6.9.13-51 and 7.1.2-26 allows remote unauthenticated attackers to crash image-processing services by submitting a crafted MVG image file. The root cause is a missing depth check in the MVG decoder (CWE-400), enabling unbounded recursion that exhausts stack memory. No active exploitation has been confirmed and no public exploit code has been identified at time of analysis, but the zero-friction attack surface - any application accepting image uploads with unpatched ImageMagick - makes patching a practical priority.

Technical ContextAI

ImageMagick is a widely-used open-source image processing library and CLI toolset. MVG (Magick Vector Graphics) is ImageMagick's native vector graphics format, parsed by a dedicated decoder. CWE-400 (Uncontrolled Resource Consumption) is the root cause class: the MVG decoder fails to bound recursive parsing depth when processing a specially crafted MVG document, allowing an attacker-controlled input to drive unbounded recursion until the process stack is exhausted. This is a classic parser vulnerability pattern in image codec implementations. The affected CPE cpe:2.3:a:imagemagick:imagemagick:*:*:*:*:*:*:*:* covers all platforms and editions of ImageMagick across both the legacy 6.x and current 7.x branches prior to the respective fixed releases.

RemediationAI

Upgrade to ImageMagick 6.9.13-51 (legacy branch) or 7.1.2-26 (current branch), as documented in the vendor advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-mx48-2qq3-23hf. If immediate patching is not feasible, disable MVG format support in ImageMagick's policy.xml by adding a deny policy for the MVG coder (e.g., adding a pattern deny entry for 'MVG'); this prevents the vulnerable decoder from being invoked at the cost of losing all MVG format processing capability, which is acceptable in most environments not explicitly requiring vector graphics rendering. Additionally, consider running ImageMagick in a sandboxed process (e.g., via seccomp or a restricted container) to contain crash blast radius, and restrict untrusted image input to allowlisted formats wherever architecturally possible.
