Summary
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.
A Denial of Service (DoS) vulnerability exists in ImageMagick. An attacker with write access to the OpenCL cache directory can exhaust system memory and crash the application by placing a maliciously crafted file.
This vulnerability in ImageMagick is of Low impact. Under these conditions, a specially crafted XML file can cause a memory leak, leading to resource exhaustion and a denial of service over extended periods.
Red Hat severity: Low — CVSS 1.9 (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-401.

Mitigation checklist
- To mitigate this, restrict write access to the OpenCL cache directory to prevent unauthorized or malformed files from being introduced. Additionally, configure process-level memory limits (using mechanisms like ulimit, cgroups, or systemd directives) for ImageMagick to contain potential memory exhaustion and safeguard overall system stability.
