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

  - A security feature bypass vulnerability exists in Device
    Guard due to improper validation of certain elements in
    a signed PowerShell script. An unauthenticated, remote
    attacker can exploit this vulnerability to modify the
    contents of a PowerShell script without invalidating the
    signature associated with the file, allowing the
    execution of a malicious script. (CVE-2017-0007)

  - A denial of service vulnerability exists in the
    Microsoft Server Message Block 2.0 and 3.0 (SMBv2/SMBv3)
    client implementations due to improper handling of
    certain requests sent to the client. An unauthenticated,
    remote attacker can exploit this issue, via a malicious
    SMB server, to cause the system to stop responding until
    it is manually restarted. (CVE-2017-0016)

  - A remote code execution vulnerability exists due to
    using an insecure path to load certain dynamic link
    library (DLL) files. A local attacker can exploit this,
    via a specially crafted library placed in the path, to
    execute arbitrary code. (CVE-2017-0039)

  - An information disclosure vulnerability exists in
    Windows dnsclient due to improper handling of certain
    requests. An unauthenticated, remote attacker can
    exploit this, by convincing a user to visit a specially
    crafted web page, to gain access to sensitive
    information on a targeted workstation. If the target is
    a server, the attacker can also exploit this issue by
    tricking the server into sending a DNS query to a
    malicious DNS server. (CVE-2017-0057)

  - An elevation of privilege vulnerability exists in
    Helppane.exe due to a failure by an unspecified DCOM
    object, configured to run as the interactive user, to
    properly authenticate the client. An authenticated,
    remote attacker can exploit this, via a specially
    crafted application, to execute arbitrary code in
    another user's session. (CVE-2017-0100)

  - An integer overflow condition exists in the iSNS Server
    service due to improper validation of input from the
    client. An unauthenticated, remote attacker can exploit
    this issue, via a specially crafted application that
    connects and issues requests to the iSNS server, to
    execute arbitrary code in the context of the SYSTEM
    account. (CVE-2017-0104)");
