ImageMagick before 7.1.2-13 contains a memory leak vulnerability in LoadOpenCLDeviceBenchmark() function when parsing malformed OpenCL device profile XML files with unclosed device elements. Attackers with write access to the OpenCL cache directory can place malicious XML files to exhaust memory and cause denial of service.
AnalysisAI
Memory exhaustion denial of service in ImageMagick before 7.1.2-13 allows a local attacker with write access to the OpenCL cache directory to crash the application by placing malformed XML files that trigger an unpatched memory leak in LoadOpenCLDeviceBenchmark(). The root cause is CWE-401: memory allocated during XML parsing of unclosed device elements is never freed, enabling a resource exhaustion attack. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions, all of which must be satisfied simultaneously. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 1.8 is consistent with the attack profile and accurately reflects minimal real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker who has gained write access to the OpenCL cache directory - perhaps through a misconfigured shared-hosting environment, a co-located container with a mounted cache volume, or a partially-compromised local account - places a crafted XML file containing malformed, unclosed OpenCL device elements. When ImageMagick subsequently performs any operation that loads the OpenCL benchmark profile, the memory leak is triggered; if the attacker can force repeated reloads (e.g., via a script that invokes ImageMagick in a loop), heap exhaustion causes the ImageMagick process or the hosting application (e.g., a PHP image-processing pipeline) to terminate. … |
| Remediation | Upgrade ImageMagick to version 7.1.2-13 or later, which incorporates the fix from upstream commit a52c1b402be08ef8ae193f28ac5b2e120f2fa26f (https://github.com/ImageMagick/ImageMagick/commit/a52c1b402be08ef8ae193f28ac5b2e120f2fa26f). … Detailed patch versions, workarounds, and compensating controls in full report. |
