"The remote Windows host is missing security update 4074587
or cumulative update 4074598. It is, therefore, affected by
multiple vulnerabilities :

  - A remote code execution vulnerability exists in the way
    that the scripting engine handles objects in memory in
    Internet Explorer. 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-2018-0866)

  - 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-2018-0757, CVE-2018-0829, CVE-2018-0830)

  - An information disclosure vulnerability exists when
    VBScript improperly discloses the contents of its
    memory, which could provide an attacker with information
    to further compromise the users computer or data.
    (CVE-2018-0847)

  - A remote code execution vulnerability exists in
    StructuredQuery when the software fails to properly
    handle objects in memory. An attacker who successfully
    exploited the vulnerability could run arbitrary code in
    the context of the current user. If the current user is
    logged on with administrative user rights, an attacker
    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-2018-0825)

  - An elevation of privilege vulnerability exists in the
    way that the Windows Kernel handles objects in memory.
    An attacker who successfully exploited the vulnerability
    could execute code with elevated permissions.
    (CVE-2018-0742, CVE-2018-0820)

  - A remote code execution vulnerability exists when
    Windows improperly handles objects in memory. An
    attacker who successfully exploited these
    vulnerabilities could take control of an affected
    system.  (CVE-2018-0842)

  - An elevation of privilege vulnerability exists when the
    Windows Common Log File System (CLFS) driver improperly
    handles objects in memory. An attacker who successfully
    exploited this vulnerability could run processes in an
    elevated context.  (CVE-2018-0844, CVE-2018-0846)

  - A remote code execution vulnerability exists in the way
    the scripting engine handles objects in memory in
    Microsoft browsers. 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-2018-0840)

  - An information disclosure vulnerability exists in the
    way that the Microsoft Windows Embedded OpenType (EOT)
    font engine parses specially crafted embedded fonts. An
    attacker who successfully exploited this vulnerability
    could potentially read data that was not intended to be
    disclosed. Note that while this vulnerability would not
    allow an attacker to either execute code or to elevate
    user rights directly, it could be used to obtain
    information in an attempt to further compromise the
    affected system.  (CVE-2018-0755, CVE-2018-0760,
    CVE-2018-0761, CVE-2018-0855)");
