DescriptionCVE.org

ImageMagick before 7.1.2-26 and 6.9.13-51 is missing a check for the allowed memory allocation limit in matrix-backed operations such as -canny. An attacker can supply a crafted image that causes ImageMagick to allocate more memory than permitted by the configured policy, resulting in a denial of service.

AnalysisAI

Memory allocation policy bypass in ImageMagick's matrix-backed operations allows a crafted image to exhaust process memory and cause a denial of service. Affected across both the version 7 series (before 7.1.2-26) and the legacy version 6 series (before 6.9.13-51), the flaw arises because operations such as -canny fail to enforce the memory ceiling set in the configured policy, nullifying a key security control. No public exploit code or active exploitation has been identified at time of analysis, and the CVSS 4.0 score of 4.8 reflects a local attack vector requiring user interaction, keeping real-world exposure moderate.

Technical ContextAI

ImageMagick's policy.xml mechanism allows administrators to cap resource usage - including memory - for image processing operations. CWE-770 (Allocation of Resources Without Limits or Throttling) describes the root cause: matrix-backed operations such as Canny edge detection allocate working memory internally without consulting the configured policy limit, so a specially crafted image with parameters that demand a large matrix can cause unchecked allocation growth. Affected software is identified by CPE cpe:2.3:a:imagemagick:imagemagick:*:*:*:*:*:*:*:* spanning the 6.x and 7.x branches. The vulnerability is local in attack vector (CVSS 4.0 AV:L), meaning the crafted image must be processed on the target system, typically through a CLI invocation, batch pipeline, or a server-side application that shells out to ImageMagick.

RemediationAI

Upgrade to ImageMagick 7.1.2-26 or later for version 7 deployments, and to 6.9.13-51 or later for version 6 deployments, per the vendor advisory GHSA-rvhp-75f6-9jqh. As a compensating control prior to patching, restrict which ImageMagick operations are permitted via policy.xml by disabling or limiting the -canny operator and similar matrix-backed morphology/edge-detection operations (e.g., set memory resource to a hard cap lower than available RAM, and consider setting 'rights="none"' for the relevant coders). Note that disabling these operations may break legitimate workflows that rely on them. Additionally, environments processing untrusted images should run ImageMagick inside a resource-constrained container or process with cgroup memory limits as a defense-in-depth measure - this directly caps the blast radius of any memory allocation bypass to the container's ceiling rather than the host.
