"The remote Windows host is affected by multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"The remote Windows host is missing security updates. It is,
therefore, affected by multiple vulnerabilities :

  - An elevation of privilege vulnerability exists when the
    Windows kernel fails to properly handle objects in
    memory. An attacker who successfully exploited this
    vulnerability could run arbitrary code in kernel mode.
    An attacker could then install programs; view, change,
    or delete data; or create new accounts with full user
    rights.  (CVE-2018-8224)

  - An elevation of privilege vulnerability exists when the
    (Human Interface Device) HID Parser Library driver
    improperly handles objects in memory. An attacker who
    successfully exploited this vulnerability could run
    processes in an elevated context.  (CVE-2018-8169)

  - A remote code execution vulnerability exists in Windows
    Domain Name System (DNS) DNSAPI.dll when it fails to
    properly handle DNS responses. An attacker who
    successfully exploited the vulnerability could run
    arbitrary code in the context of the Local System
    Account.  (CVE-2018-8225)

  - A denial of service vulnerability exists in the way that
    the Windows Code Integrity Module performs hashing. An
    attacker who successfully exploited the vulnerability
    could cause a system to stop responding. Note that the
    denial of service condition would not allow an attacker
    to execute code or to elevate user privileges. However,
    the denial of service condition could prevent authorized
    users from using system resources. An attacker could
    host a specially crafted file in a website or SMB share.
    The attacker could also take advantage of compromised
    websites, or websites that accept or host user-provided
    content or advertisements, by adding specially crafted
    content that could exploit the vulnerability. However,
    in all cases an attacker would have no way to force
    users to view the attacker-controlled content. Instead,
    an attacker would have to convince users to take action,
    typically via an enticement in email or instant message,
    or by getting them to open an email attachment. The
    security update addresses the vulnerability by modifying
    how the Code Integrity Module performs hashing.
    (CVE-2018-1040)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2018-8207)

  - An elevation of privilege vulnerability exists when NTFS
    improperly checks access. An attacker who successfully
    exploited this vulnerability could run processes in an
    elevated context.  (CVE-2018-1036)");
