"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 validation of user-supplied input before
    loading DLL files. A local attacker can exploit these,
    via a crafted application, to elevate their privileges
    and take control of the affected system. (CVE-2016-0014,
    CVE-2016-0020)

  - A remote code execution vulnerability exists in
    DirectShow due to improper validation of user-supplied
    input. A remote attacker can exploit this, by convincing
    a user to open a specially crafted file, to execute
    arbitrary code in the context of the current user,
    resulting in taking control of the affected system.
    (CVE-2016-0015)

  - Multiple remote code execution vulnerabilities exist
    due to improper validation of user-supplied input before
    loading DLL files. A local attacker can exploit these,
    via a specially crafted application, to execute
    arbitrary code. (CVE-2016-0016, CVE-2016-0018)

  - A security bypass vulnerability exists in the Windows
    Remote Desktop Protocol (RDP) due to a failure to
    prevent remote logons to accounts that have no passwords
    set. A remote attacker can exploit this, by using an
    older version of the RDP client to connect to a Windows
    10 host, to generate a list of user accounts.
