Mitigation checklist
- Do not process untrusted image files with ImageMagick. If processing of untrusted input is required, configure ImageMagick's policy.xml to set memory and map resource limits to contain the impact of potential memory leaks. Upgrade to ImageMagick 7.1.2-26 or 6.9.13-51 mitigates the issue.
