Anyone can enter the open door and cause harm to you. Similarly, there are no patched vulnerabilities in your system that can harm your system. The open source community, unlike the patent world, responds fairly quickly to bug fixes, so if you keep your system up to date, you'll get security.

Read the change log carefully to make sure the update doesn't break your custom service.
