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, when providing invalid arguments to the connected-components option an infinite loop will occur. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.

AnalysisAI

Uncontrolled resource consumption in ImageMagick (all versions prior to 6.9.13-51 and 7.1.2-26) allows a denial-of-service condition by supplying invalid arguments to the connected-components processing option, which causes an infinite loop that exhausts CPU resources indefinitely. The vulnerability requires local access, user interaction, and high attack complexity, confining realistic risk to environments where untrusted input can influence ImageMagick invocations - such as automated image-processing pipelines or web applications that expose connected-components functionality. Vendor-released patches exist for both the 6.x and 7.x branches; no public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis.

Technical ContextAI

ImageMagick is a ubiquitous open-source image processing library and CLI toolset used across web stacks, content management systems, and media pipelines. The vulnerable component is the connected-components feature (invoked via the -connected-components flag), which performs image segmentation by labeling contiguous regions of pixels. CWE-400 (Uncontrolled Resource Consumption) describes the root cause: the processing loop lacks an exit condition when fed invalid arguments, causing it to spin indefinitely rather than returning an error or bounds-checking the input. The affected CPE cpe:2.3:a:imagemagick:imagemagick:*:*:*:*:*:*:*:* covers all platform variants of ImageMagick across both the legacy 6.x and current 7.x release lines up to the respective fix versions.

RemediationAI

Upgrade ImageMagick to version 6.9.13-51 or later on the 6.x branch, or to version 7.1.2-26 or later on the 7.x branch; these are the vendor-confirmed fixed releases per GitHub Security Advisory GHSA-qhmf-7fc4-8q3h at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-qhmf-7fc4-8q3h. If immediate patching is not feasible, the most targeted compensating control is to avoid invoking the -connected-components option on untrusted or unvalidated input - removing that code path entirely eliminates the vulnerable surface. For environments where connected-components processing is required on untrusted data, apply OS-level CPU time limits (e.g., ulimit -t on Linux, or cgroup CPU quotas) to constrain the impact of the infinite loop to a bounded hang rather than a full host denial of service; note this does not prevent the loop from triggering, only caps its damage. Running ImageMagick in a sandboxed process or container with strict resource limits provides defense-in-depth regardless of patch status.
