Device Guard in Windows 10 Gold, 1511, 1607, 1703, and 1709, Windows Server 2016, and Windows Server, version 1709 allows an attacker to make an unsigned file appear to be signed, due to a security feature bypass, aka Device Guard Security Feature Bypass Vulnerability.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
