Mitigation checklist
- Avoid loading untrusted font files with Pillow. If processing font files from untrusted sources is required, implement application-level resource limits (e.g., cgroups, ulimit) to restrict memory allocation per process. Upgrading to Pillow 12.3.0 or later resolves this issue.
