"The remote Windows host is affected by multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"The remote Windows host is missing security update 4457984
or cumulative update 4458010. It is, therefore, affected by
multiple vulnerabilities :

  - An information disclosure vulnerability exists in
    Windows when the Windows bowser.sys kernel-mode driver
    fails to properly handle objects in memory. An attacker
    who successfully exploited the vulnerability could
    potentially disclose contents of System memory.
    (CVE-2018-8271)

  - An information disclosure vulnerability exists when the
    Windows GDI component improperly discloses the contents
    of its memory. An attacker who successfully exploited
    the vulnerability could obtain information to further
    compromise the users system. There are multiple ways an
    attacker could exploit the vulnerability, such as by
    convincing a user to open a specially crafted document,
    or by convincing a user to visit an untrusted webpage.
    The security update addresses the vulnerability by
    correcting how the Windows GDI component handles objects
    in memory. (CVE-2018-8424)

  - A buffer overflow vulnerability exists in the Microsoft
    JET Database Engine that could allow remote code
    execution on an affected system. An attacker who
    successfully exploited this vulnerability could take
    control of an affected system. An attacker could then
    install programs; view, change, or delete data; or
    create new accounts with full user rights. Users whose
    accounts are configured to have fewer user rights on the
    system could be less impacted than users who operate
    with administrative user rights.  (CVE-2018-8392,
    CVE-2018-8393)

  - A remote code execution vulnerability exists when
    Windows does not properly handle specially crafted image
    files. An attacker who successfully exploited the
    vulnerability could execute arbitrary code.
    (CVE-2018-8475)

  - A remote code execution vulnerability exists when the
    Microsoft XML Core Services MSXML parser processes user
    input. An attacker who successfully exploited the
    vulnerability could run malicious code remotely to take
    control of the users system.  (CVE-2018-8420)

  - An information disclosure vulnerability exists when the
    Windows Graphics component improperly handles objects in
    memory. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the users system. An authenticated attacker
    could exploit this vulnerability by running a specially
    crafted application. The update addresses the
    vulnerability by correcting how the Windows Graphics
    Component handles objects in memory. (CVE-2018-8433)

  - A remote code execution vulnerability exists when
    Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the
    context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2018-8447)

  - An elevation of privilege vulnerability exists when
    Windows improperly handles calls to Advanced Local
    Procedure Call (ALPC). An attacker who successfully
    exploited this vulnerability could run arbitrary code in
    the security context of the local system. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2018-8440)

  - 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. An authenticated attacker could exploit this
    vulnerability by running a specially crafted
    application. The update addresses the vulnerability by
    correcting how the Windows kernel handles objects in
    memory. (CVE-2018-8442, CVE-2018-8443)

  - An information disclosure vulnerability exists when the
    Windows kernel fails to properly initialize a memory
    address. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the users system.  (CVE-2018-8419)

  - An information disclosure vulnerability exists when
    Windows Hyper-V on a host operating system fails to
    properly validate input from an authenticated user on a
    guest operating system.  (CVE-2018-8434)

  - A remote code execution vulnerability exists when the
    Windows font library improperly handles specially
    crafted embedded fonts. An attacker who successfully
    exploited this vulnerability could take control of the
    affected system. An attacker could then install
    programs; view, change, or delete data; or create new
    accounts with full user rights.  (CVE-2018-8332)

  - An elevation of privilege vulnerability exists in
  Windows that allows a sandbox escape. An attacker who
  successfully exploited the vulnerability could use the
  sandbox escape to elevate privileges on an affected
  system. This vulnerability by itself does not allow
  arbitrary code execution. However, the vulnerability
  could allow arbitrary code to run if an attacker uses it
  in combination with another vulnerability, such as a
  remote code execution vulnerability or another elevation
  of privilege vulnerability, that can leverage the
  elevated privileges when code execution is attempted.
  The security update addresses the vulnerability by
  correcting how Windows parses files. (CVE-2018-8468)

  - A remote code execution vulnerability exists when
    Microsoft .NET Framework processes input. An attacker
    who successfully exploited this vulnerability could take
    control of an affected system.  (CVE-2018-8421)

  - 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-2018-8336, CVE-2018-8446)");
