✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Until a fixed package is available, restrict membership in CA Administrator and equivalent roles to fully trusted operators, and audit certificate profile import operations for unexpected or unrecognized profile content. Review any custom ExternalProcessConstraint executable configuration in Dogtag for unnecessary exposure.
