"The remote Windows host is running a version of the Windows kernel
that is affected by one or more of the following vulnerabilities :

  - A buffer overflow in the 'GreEnableEUDC()' function can
    be triggered using specially crafted end-user-defined
    characters (EUDC) registry key values. (CVE-2010-4398)

  - An integer truncation vulnerability exists due to the
    failure of the Windows kernel to validate user-supplied
    data before allocating memory. (CVE-2011-0045)

An attacker with local access to the affected system can exploit these
issues to execute arbitrary code in kernel mode and take complete
control of the affected system.");
