Mitigation checklist

Recommended fix / mitigation

To mitigate the potential for denial of service, system administrators can enforce resource limits for users who execute ImageMagick. This can be achieved by setting appropriate `ulimit` values for memory consumption (e.g., `as` for virtual memory or `rss` for resident set size) in user login scripts or system-wide configuration files like `/etc/security/limits.conf`. For example, to limit virtual memory for a user, add a line such as `username hard as 1048576` (1GB) to `/etc/security/limits.conf`. Changes to `/etc/security/limits.conf` require users to log out and back in to take effect and may impact other applications run by the user.
