"The remote Windows host is missing security update 4284819.
It is, therefore, affected by multiple vulnerabilities :

  - 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 denial of service vulnerability exists when Microsoft
    Hyper-V Network Switch on a host server fails to
    properly validate input from a privileged user on a
    guest operating system. An attacker who successfully
    exploited the vulnerability could cause the host server
    to crash.  (CVE-2018-8218)

  - A memory corruption vulnerability exists when Windows
    Media Foundation improperly handles objects in memory.
    An attacker who successfully exploited the vulnerability
    could install programs; view, change, or delete data; or
    create new accounts with full user rights. 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 a malicious webpage. The security update addresses
    the vulnerability by correcting how Windows Media
    Foundation handles objects in memory. (CVE-2018-8251)

  - A denial of service vulnerability exists when Windows
    improperly handles objects in memory. An attacker who
    successfully exploited the vulnerability could cause a
    target system to stop responding.  (CVE-2018-8205)

  - An denial of service vulnerability exists when Windows
    NT WEBDAV Minirdr attempts to query a WEBDAV directory.
    An attacker who successfully exploited the vulnerability
    could cause a denial of service.  (CVE-2018-8175)

  - 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-2018-8239)

  - A remote code execution vulnerability exists when HTTP
    Protocol Stack (Http.sys) improperly handles objects in
    memory. An attacker who successfully exploited this
    vulnerability could execute arbitrary code and take
    control of the affected system.  (CVE-2018-8231)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly initializes objects in memory.
    (CVE-2018-8121)

  - A security feature bypass vulnerability exists in Device
    Guard that could allow an attacker to inject malicious
    code into a Windows PowerShell session. An attacker who
    successfully exploited this vulnerability could inject
    code into a trusted PowerShell process to bypass the
    Device Guard Code Integrity policy on the local machine.
    (CVE-2018-8201, CVE-2018-8211, CVE-2018-8212,
    CVE-2018-8215, CVE-2018-8221)

  - An information disclosure vulnerability exists when
    Microsoft Edge improperly handles objects in memory. An
    attacker who successfully exploited the vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2018-8234)

  - An Elevation of Privilege vulnerability exists when
    Cortana retrieves data from user input services without
    consideration for status. An attacker who successfully
    exploited the vulnerability could execute commands with
    elevated permissions.  (CVE-2018-8140)

  - A denial of service vulnerability exists in the HTTP 2.0
    protocol stack (HTTP.sys) when HTTP.sys improperly
    parses specially crafted HTTP 2.0 requests. An attacker
    who successfully exploited the vulnerability could
    create a denial of service condition, causing the target
    system to become unresponsive.  (CVE-2018-8226)

  - 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-2018-8267)

  - 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)

  - 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 security feature bypass vulnerability exists when
    Microsoft Edge improperly handles requests of different
    origins. The vulnerability allows Microsoft Edge to
    bypass Same-Origin Policy (SOP) restrictions, and to
    allow requests that should otherwise be ignored. An
    attacker who successfully exploited the vulnerability
    could force the browser to send data that would
    otherwise be restricted.  (CVE-2018-8235)

  - A remote code execution vulnerability exists in the way
    that the Chakra scripting engine handles objects in
    memory in Microsoft Edge. 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-2018-8227, CVE-2018-8229)

  - A remote code execution vulnerability exists when
    Microsoft Edge improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that enables an attacker to 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-2018-8111,
    CVE-2018-8236)

  - An information disclosure vulnerability exists when
    Windows allows a normal user to access the Wireless LAN
    profile of an administrative user. An authenticated
    attacker who successfully exploited the vulnerability
    could access the Wireless LAN profile of an
    administrative user, including passwords for wireless
    networks. An attacker would need to log on to the
    affected system and run a specific command. The security
    update addresses the vulnerability by changing the way
    that Windows enforces access permissions to Wireless LAN
    profiles. (CVE-2018-8209)

  - 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-2018-0978)

  - An elevation of privilege vulnerability exists when
    Windows Hyper-V instruction emulation fails to properly
    enforce privilege levels. An attacker who successfully
    exploited this vulnerability could gain elevated
    privileges on a target guest operating system. The host
    operating system is not vulnerable to this attack. This
    vulnerability by itself does not allow arbitrary code to
    be run. However, the vulnerability could be used in
    conjunction with one or more vulnerabilities (e.g. a
    remote code execution vulnerability and another
    elevation of privilege) that could take advantage of the
    elevated privileges when running. The update addresses
    the vulnerability by correcting how privileges are
    enforced by Windows Hyper-V instruction emulation.
    (CVE-2018-8219)

  - An information disclosure vulnerability exists when Edge
    improperly marks files. An attacker who successfully
    exploited this vulnerability could exfiltrate file
    contents from disk. For an attack to be successful, an
    attacker must persuade a user to open a malicious
    website. The security update addresses the vulnerability
    by properly marking files. (CVE-2018-0871)

  - 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)

  - A security feature bypass vulnerability exists in
    Internet Explorer that allows for bypassing Mark of the
    Web Tagging (MOTW). Failing to set the MOTW means that a
    large number of Microsoft security technologies are
    bypassed.  (CVE-2018-8113)

  - 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-2018-8210, CVE-2018-8213)

  - An elevation of privilege vulnerability exists in the
    way that the Windows Kernel API enforces permissions. An
    attacker who successfully exploited the vulnerability
    could impersonate processes, interject cross-process
    communication, or interrupt system functionality.
    (CVE-2018-0982)

  - An elevation of privilege vulnerability exists in
    Windows when Desktop Bridge does not properly manage the
    virtual registry. 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-2018-8208, CVE-2018-8214)");

    create a denial of service condition, causing the target
    system to become unresponsive.  (CVE-2018-8226)

  - 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-2018-8267)

  - 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 in
    Windows when the Win32k component 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-2018-8233)

  - 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)

  - 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 security feature bypass vulnerability exists when
    Microsoft Edge improperly handles requests of different
    origins. The vulnerability allows Microsoft Edge to
    bypass Same-Origin Policy (SOP) restrictions, and to
    allow requests that should otherwise be ignored. An
    attacker who successfully exploited the vulnerability
    could force the browser to send data that would
    otherwise be restricted.  (CVE-2018-8235)

  - A remote code execution vulnerability exists in the way
    that the Chakra scripting engine handles objects in
    memory in Microsoft Edge. 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-2018-8227, CVE-2018-8229)

  - 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-2018-0978)

  - An elevation of privilege vulnerability exists when
    Windows Hyper-V instruction emulation fails to properly
    enforce privilege levels. An attacker who successfully
    exploited this vulnerability could gain elevated
    privileges on a target guest operating system. The host
    operating system is not vulnerable to this attack. This
    vulnerability by itself does not allow arbitrary code to
    be run. However, the vulnerability could be used in
    conjunction with one or more vulnerabilities (e.g. a
    remote code execution vulnerability and another
    elevation of privilege) that could take advantage of the
    elevated privileges when running. The update addresses
    the vulnerability by correcting how privileges are
    enforced by Windows Hyper-V instruction emulation.
    (CVE-2018-8219)

  - A remote code execution vulnerability exists when
    Microsoft Edge improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that enables an attacker to 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-2018-8110,
    CVE-2018-8236)

  - An information disclosure vulnerability exists when Edge
    improperly marks files. An attacker who successfully
    exploited this vulnerability could exfiltrate file
    contents from disk. For an attack to be successful, an
    attacker must persuade a user to open a malicious
    website. The security update addresses the vulnerability
    by properly marking files. (CVE-2018-0871)

  - 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)

  - A security feature bypass vulnerability exists in
    Internet Explorer that allows for bypassing Mark of the
    Web Tagging (MOTW). Failing to set the MOTW means that a
    large number of Microsoft security technologies are
    bypassed.  (CVE-2018-8113)

  - 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-2018-8210, CVE-2018-8213)

  - An elevation of privilege vulnerability exists in the
    way that the Windows Kernel API enforces permissions. An
    attacker who successfully exploited the vulnerability
    could impersonate processes, interject cross-process
    communication, or interrupt system functionality.
    (CVE-2018-0982)

  - An elevation of privilege vulnerability exists in
    Windows when Desktop Bridge does not properly manage the
    virtual registry. 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-2018-8208, CVE-2018-8214)");
