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

  - Multiple elevation of privilege vulnerabilities exist
    due to improper handling of session objects. A local
    attacker can exploit these, via a specially crafted
    application, to hijack the session of another user.
    (CVE-2016-3305, CVE-2016-3306)

  - A flaw exists in the Windows Kernel API due to improper
    enforcement of permissions. A local attacker can exploit
    this, via a specially crafted application, to elevate
    privileges and thereby disclose potentially sensitive
    information. (CVE-2016-3371)

  - An elevation of privilege vulnerability exists in the
    Windows Kernel API due to improper enforcement of
    permissions. A local attacker can exploit this, via a
    specially crafted application, to impersonate processes,
    interject cross-process communication, or interrupt
    system functionality. (CVE-2016-3372)

  - A flaw exists in the Windows Kernel API due to
    improperly allowing access to sensitive registry
    information. A local attacker can exploit this, via a
    specially crafted application, to elevate privileges
    and thereby gain access to user account information.
