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

  - An elevation of privilege vulnerability exists due to a
    failure to properly enforce permissions when loading
    specially crafted DLLs. A local attacker can exploit
    this vulnerability to execute arbitrary code with
    administrator privileges. (CVE-2016-3346)

  - An information disclosure vulnerability exists due to a
    failure to properly validate NT LAN Manager (NTLM)
    Single Sign-On (SSO) requests during Microsoft Account
    (MSA) login sessions. An unauthenticated, remote
    attacker can exploit this vulnerability, by convincing a
    user to load a malicious document that initiates an NTLM
    SSO validation request or to visit a malicious website
    or SMB / UNC path destination, to disclose a user's NTLM
    password hash. (CVE-2016-3352)

  - A remote code execution vulnerability exists due to
    improper handling of objects in memory. A remote
    attacker with a domain user account can exploit this
    vulnerability, via a specially crafted request, to
    execute arbitrary code with elevated permissions.
    (CVE-2016-3368)

  - A denial of service vulnerability exists due to improper
    handling of objects in memory. An unauthenticated,
    remote attacker can exploit this to cause the system to
    stop responding. (CVE-2016-3369)");
