Lifecycle Timeline
2DescriptionCVE.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. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The vulnerable code path is triggered only when a matrix-backed ImageMagick operation (explicitly named in the description as -canny and similar) is invoked against a crafted image. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 4.8 with vector AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L accurately reflects a limited-impact vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker submits a specially crafted image file - for example, through an upload form that feeds into a server-side ImageMagick pipeline performing edge detection with -canny - causing ImageMagick to allocate memory far beyond the policy limit. If the process is not cgroup-constrained, this can exhaust available memory on the host, crashing the ImageMagick worker and potentially disrupting the wider application. … |
| Remediation | 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. … Detailed patch versions, workarounds, and compensating controls in full report. |
