"The remote Windows host is missing a security update. It is,
therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in the
    Windows graphics device interface due to improper
    handling of objects in memory. An attacker can exploit
    this to bypass the Address Space Layout Randomization
    (ASLR) feature, resulting in the ability to predict
    memory offsets in a call stack. (CVE-2016-0008)

  - A remote code execution vulnerability exists due to
    improper handling of objects in memory. An attacker can
    exploit this vulnerability by convincing a user to visit
    a specially crafted website, resulting in execution of
    arbitrary code in the context of the current user.
    (CVE-2016-0008)");

Note that Windows 10 with Citrix XenDesktop installed will not be

prevents users from logging on when the patch is applied. To apply the
patch you must first uninstall XenDesktop or contact Citrix for help
with the issue.");
