"The remote Windows host is missing a security update. It is,

  - Multiple privilege escalation vulnerabilities exist in
    the Windows kernel-mode driver due to a failure to
    properly handle objects in memory. An authenticated,
    remote attacker can exploit this, via a crafted
    application, to execute arbitrary code. (CVE-2016-0171,
    CVE-2016-0173, CVE-2016-0174, CVE-2016-0196)

  - A security feature bypass vulnerability exists in the
    Windows kernel. An authenticated, remote attacker can
    exploit this, via a crafted application, to bypass
    the Kernel Address Space Layout Randomization (KASLR)
    feature and retrieve the memory address of a kernel
    object. (CVE-2016-0175)

  - A privilege escalation vulnerability exists in the
    DirectX Graphics kernel subsystem due to a failure to
    properly handle objects in memory. An authenticated,
    remote attacker can exploit this, via a crafted
    application, to execute arbitrary code. (CVE-2016-0176)

  - A privilege escalation vulnerability exists in the
    DirectX Graphics kernel subsystem due to a failure to
    correctly map kernel memory and to handle objects in
    memory. An authenticated, remote attacker can exploit
    this, via a crafted application, to execute arbitrary
    code. (CVE-2016-0197)");
