The vulnerability could allow an attacker to execute arbitrary code and take complete control of an affected system. Supported editions of Microsoft Windows are not delivered with any RPC servers or clients that are subject to exploitation of this vulnerability. In a default configuration, users could not be attacked by exploitation of this vulnerability.
