DescriptionCVE.org

ImageMagick before 7.1.2-15 contains a memory leak vulnerability in multiple coders that write raw pixel data where allocated objects are not properly freed. Attackers can trigger this leak by processing specially crafted images, causing memory exhaustion and denial of service.

AnalysisAI

Memory exhaustion via unfreed heap allocations in ImageMagick before 7.1.2-15 enables remote denial of service against services that process untrusted images through the affected raw-pixel-data coders. The flaw (CWE-401) causes 160-byte objects to accumulate on the heap with each crafted image processed, progressively starving the host process of memory. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Submit crafted image to exposed processing endpoint
Delivery
Invoke vulnerable raw-pixel-data coder in ImageMagick
Exploit
Trigger heap allocation without deallocation (160 bytes per image)
Execution
Repeat submissions to accumulate memory pressure
Persist
Exhaust host process memory
Impact
Service becomes unresponsive (DoS)

Vulnerability AssessmentAI

Exploitation The target application must pass attacker-controlled image data to one of the ImageMagick coders that write raw pixel data - the specific coder names are not individually enumerated in available intelligence beyond 'coders that write raw pixel data.' No authentication is required (PR:N, UI:N per the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N yields a score of 6.3, reflecting a meaningful but constrained threat. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with access to an image upload endpoint submits a repeated sequence of specially crafted image files engineered to invoke one of the vulnerable raw-pixel-data coders, each causing a 160-byte heap leak per the GHSA trace. Over hundreds or thousands of requests, heap memory is progressively exhausted until the ImageMagick process or its host service crashes or becomes unresponsive, denying service to legitimate users. …
Remediation Upgrade ImageMagick to version 7.1.2-15 or later; the upstream fix is confirmed at commit fe0a49a58ac5b7a18ff2618b6207dcad71123e43 (https://github.com/ImageMagick/ImageMagick/commit/fe0a49a58ac5b7a18ff2618b6207dcad71123e43) per the GHSA advisory (https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-wfx3-6g53-9fgc). … Detailed patch versions, workarounds, and compensating controls in full report.
