Frequently Asked Questions

When is a server exposed to exploitation?

A machine is exposed while it is network booting with PXE enabled and can receive a crafted ICMP error. The discussion notes that provisioning networks may not be as isolated as intended.

Does Secure Boot prevent this attack?

No. The reported code execution occurs before Secure Boot does anything.
