Description of the security update of Windows XP and Windows Server 2003: June 13, 2017 A remote code execution vulnerability exists in Remote Desktop Protocol (RDP) if the RDP server has Smart Card authentication enabled. An attacker who successfully exploited this vulnerability could execute code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit this vulnerability, an attacker would need to run a specially crafted application against an RDP server which has Smart Card authentication enabled. Smart Card authentication is a non-default configuration; systems without it enabled are not vulnerable. CVE-2017-0176
