"The remote Windows host is missing security update 4038779
or cumulative update 4038777. It is, therefore, affected by
multiple vulnerabilities :

  - A race condition that could lead to a remote code
    execution vulnerability exists in NetBT Session Services
    when NetBT fails to maintain certain sequencing
    requirements. (CVE-2017-0161)

  - A spoofing vulnerability exists in Microsoft's
    implementation of the Bluetooth stack. An attacker who
    successfully exploited this vulnerability could perform
    a man-in-the-middle attack and force a user's computer
    to unknowingly route traffic through the attacker's
    computer. The attacker can then monitor and read the
    traffic before sending it on to the intended recipient.
    (CVE-2017-8628)

  - An elevation of privilege vulnerability exists in
    Windows when the Windows kernel-mode driver 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. To exploit
    this vulnerability, an attacker would first have to log
    on to the system. An attacker could then run a specially
    crafted application that could exploit the vulnerability
    and take control of an affected system. The update
    addresses this vulnerability by correcting how the
    Windows kernel-mode driver handles objects in memory.
    (CVE-2017-8675)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability. (CVE-2017-8676)

  - 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-2017-8682)

  - An information disclosure vulnerability exists when the
    Microsoft Windows Graphics Component improperly handles
    objects in memory. An attacker who successfully
    exploited the vulnerability could obtain information to
    further compromise the users system. (CVE-2017-8683)

  - A information disclosure vulnerability exists when the
    Windows GDI+ component improperly discloses kernel
    memory addresses. An attacker who successfully exploited
    the vulnerability could obtain information to further
    compromise the users system.
    (CVE-2017-8677, CVE-2017-8680, CVE-2017-8681,
    CVE-2017-8684, CVE-2017-8685)

  - An Information disclosure vulnerability exists in
    Windows kernel that could allow an attacker to retrieve
    information that could lead to a Kernel Address Space
    Layout Randomization (KASLR) bypass. An attacker who
    successfully exploited this vulnerability could retrieve
    the memory address of a kernel object. (CVE-2017-8687)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface+ (GDI+)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability. (CVE-2017-8688)

  - An information disclosure vulnerability exists when
    Windows Uniscribe 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 update addresses the vulnerability by correcting how
    Windows Uniscribe handles objects in memory.
    (CVE-2017-8695)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. 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-2017-8696)

  - A remote code execution vulnerability exists when
    Windows Shell does not properly validate file copy
    destinations. An attacker who successfully exploited the
    vulnerability could run arbitrary code in the context of
    the current user.
    (CVE-2017-8699)

  - 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-2017-8707)

  - An information disclosure vulnerability exists when the
    Windows kernel fails to properly initialize a memory
    address, allowing an attacker to retrieve information
    that could lead to a Kernel Address Space Layout
    Randomization (KASLR) bypass. An attacker who
    successfully exploited this vulnerability could retrieve
    the base address of the kernel driver from a compromised
    process. (CVE-2017-8708)

  - An information disclosure vulnerability exists in the
    Windows System Information Console when it improperly
    parses XML input containing a reference to an external
    entity. An attacker who successfully exploited this
    vulnerability could read arbitrary files via an XML
    external entity (XXE) declaration. To exploit the
    vulnerability, an attacker could create a file
    containing specially crafted XML content and convince an
    authenticated user to open the file. The update
    addresses the vulnerability by modifying the way that
    the Windows System Information Console parses XML input.
    (CVE-2017-8710)

  - 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-2017-8678, CVE-2017-8679, CVE-2017-8709,
    CVE-2017-8719)

  - 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-2017-8720)

  - A spoofing vulnerability exists when Internet Explorer
    improperly handles specific HTML content. An attacker
    who successfully exploited this vulnerability could
    trick a user into believing that the user was visiting a
    legitimate website. The specially crafted website could
    either spoof content or serve as a pivot to chain an
    attack with other vulnerabilities in web services. To
    exploit the vulnerability, the user must either browse
    to a malicious website or be redirected to it. In an
    email attack scenario, an attacker could send an email
    message in an attempt to convince the user to click a
    link to the malicious website. (CVE-2017-8733)

  - An information disclosure vulnerability exists in
    Microsoft browsers due to improper parent domain
    verification in certain functionality. An attacker who
    successfully exploited the vulnerability could obtain
    specific information that is used in the parent domain.
    (CVE-2017-8736)

  - A remote code execution vulnerability exists in the way
    that Microsoft browser JavaScript engines render content
    when handling 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. (CVE-2017-8741, CVE-2017-8748)

  - 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. (CVE-2017-8747,
    CVE-2017-8749)

  - A remote code execution vulnerability exists when
    Microsoft browsers improperly access 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. (CVE-2017-8750)

  - A remote code execution vulnerability exists when
    Microsoft .NET Framework processes untrusted input. An
    attacker who successfully exploited this vulnerability
    in software using the .NET framework 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. (CVE-2017-8759)

  - An information disclosure vulnerability exists in
    Microsoft browsers in the scripting engines due to
    improper handling of objects in memory. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to disclose files on a user's computer. (CVE-2017-8529)");

multiple vulnerabilities :

  - An information disclosure vulnerability exists when
    Windows Uniscribe improperly discloses the contents of

    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code

    severity is indicated as Critical in the Affected
    Products table, the Preview Pane is an attack vector for
    this vulnerability. The security update addresses the
    vulnerability by correcting how GDI handles memory
    addresses. (CVE-2017-8676)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. 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.
    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. There are
    multiple ways an attacker could exploit this
    vulnerability: In a web-based attack scenario, an
    attacker could host a specially crafted website designed
    to exploit this vulnerability and then convince a user
    to view the website. 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 by getting them to click a link
    in an email or instant message that takes users to the
    attacker's website, or by opening an attachment sent
    through email. In a file-sharing attack scenario, an
    attacker could provide a specially crafted document file
    designed to exploit this vulnerability and then convince
    a user to open the document file.The security update
    addresses the vulnerability by correcting how Windows
    Uniscribe handles objects in memory. (CVE-2017-8696)");

"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in
    Microsoft Office software when it fails to properly
    handle objects in memory. An attacker who successfully
    exploited the vulnerability could use a specially
    crafted file to perform actions in the security context
    of the current user. For example, the file could then
    take actions on behalf of the logged-on user with the
    same permissions as the current user. Exploitation of
    this vulnerability requires that a user open a specially
    crafted file with an affected version of Microsoft
    Office software. In an email attack scenario, an
    attacker could exploit the vulnerability by sending the
    specially crafted file to the user and convincing the
    user to open the file. In a web-based attack scenario,
    an attacker could host a website (or leverage a
    compromised website that accepts or hosts user-provided
    content) that contains a specially crafted file that is
    designed to exploit the vulnerability. However, an
    attacker would have no way to force the user to visit
    the website. Instead, an attacker would have to convince
    the user to click a link, typically by way of an
    enticement in an email or Instant Messenger message, and
    then convince the user to open the specially crafted
    file. The security update addresses the vulnerability by
    correcting how Microsoft Office handles files in memory.
    (CVE-2017-8630, CVE-2017-8744)

  - 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. 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. There are multiple ways an
    attacker could exploit this vulnerability. In a web-
    based attack scenario, an attacker could host a
    specially crafted website that is designed to exploit
    this vulnerability and then convince a user to view the
    website. 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 by getting them to click a link in an email
    message or in an Instant Messenger message that takes
    users to the attacker's website, or by opening an
    attachment sent through email. In a file sharing attack
    scenario, an attacker could provide a specially crafted
    document file that is designed to exploit this
    vulnerability, and then convince a user to open the
    document file. The security update addresses the
    vulnerabilities by correcting how the Windows font
    library handles embedded fonts. (CVE-2017-8682)

  - An information disclosure vulnerability exists when
    Windows Uniscribe 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 update addresses the vulnerability by correcting how
    Windows Uniscribe handles objects in memory.
    (CVE-2017-8695)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. 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.
    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. There are
    multiple ways an attacker could exploit this
    vulnerability: In a web-based attack scenario, an
    attacker could host a specially crafted website designed
    to exploit this vulnerability and then convince a user
    to view the website. 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 by getting them to click a link
    in an email or instant message that takes users to the
    attacker's website, or by opening an attachment sent
    through email. In a file-sharing attack scenario, an
    attacker could provide a specially crafted document file
    designed to exploit this vulnerability and then convince
    a user to open the document file.The security update
    addresses the vulnerability by correcting how Windows
    Uniscribe handles objects in memory. (CVE-2017-8696)

  - A remote code execution vulnerability exists in
    Microsoft Office software 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. 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.
    Exploitation of the vulnerability requires that a user
    open a specially crafted file with an affected version
    of Microsoft Office software. In an email attack
    scenario, an attacker could exploit the vulnerability by
    sending the specially crafted file to the user and
    convincing the user to open the file. In a web-based
    attack scenario, an attacker could host a website (or
    leverage a compromised website that accepts or hosts
    user-provided content) that contains a specially crafted
    file designed to exploit the vulnerability. An attacker
    would have no way to force users to visit the website.
    Instead, an attacker would have to convince users to
    click a link, typically by way of an enticement in an
    email or instant message, and then convince them to open
    the specially crafted file. Note that the Preview Pane
    is not an attack vector for this vulnerability. The
    security update addresses the vulnerability by
    correcting how Office handles objects in memory.
    (CVE-2017-8742)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability. To exploit this vulnerability, an
    attacker would have to log on to an affected system and
    run a specially crafted application. Note that where the
    severity is indicated as Critical in the Affected
    Products table, the Preview Pane is an attack vector for
    this vulnerability. The security update addresses the
    vulnerability by correcting how GDI handles memory
    addresses. (CVE-2017-8676)");

"The Microsoft Office Online Server or Microsoft Office Web
Apps installation on the remote host is missing security
updates. It is, therefore, affected by multiple
vulnerabilities :

  - A remote code execution vulnerability exists in
    Microsoft Office software when it fails to properly
    handle objects in memory. An attacker who successfully
    exploited the vulnerability could use a specially
    crafted file to perform actions in the security context
    of the current user. For example, the file could then
    take actions on behalf of the logged-on user with the
    same permissions as the current user. Exploitation of
    this vulnerability requires that a user open a specially
    crafted file with an affected version of Microsoft
    Office software. In an email attack scenario, an
    attacker could exploit the vulnerability by sending the
    specially crafted file to the user and convincing the
    user to open the file. In a web-based attack scenario,
    an attacker could host a website (or leverage a
    compromised website that accepts or hosts user-provided
    content) that contains a specially crafted file that is
    designed to exploit the vulnerability. However, an
    attacker would have no way to force the user to visit
    the website. Instead, an attacker would have to convince
    the user to click a link, typically by way of an
    enticement in an email or Instant Messenger message, and
    then convince the user to open the specially crafted
    file. The security update addresses the vulnerability by
    correcting how Microsoft Office handles files in memory.
    (CVE-2017-8631)

  - A remote code execution vulnerability exists in
    Microsoft Office software 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. 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.
    Exploitation of the vulnerability requires that a user
    open a specially crafted file with an affected version
    of Microsoft Office software. In an email attack
    scenario, an attacker could exploit the vulnerability by
    sending the specially crafted file to the user and
    convincing the user to open the file. In a web-based
    attack scenario, an attacker could host a website (or
    leverage a compromised website that accepts or hosts
    user-provided content) that contains a specially crafted
    file designed to exploit the vulnerability. An attacker
    would have no way to force users to visit the website.
    Instead, an attacker would have to convince users to
    click a link, typically by way of an enticement in an
    email or instant message, and then convince them to open
    the specially crafted file. Note that the Preview Pane
    is not an attack vector for this vulnerability. The
    security update addresses the vulnerability by
    correcting how Office handles objects in memory.
    (CVE-2017-8742, CVE-2017-8743)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. 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.
    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. There are
    multiple ways an attacker could exploit this
    vulnerability: In a web-based attack scenario, an
    attacker could host a specially crafted website designed
    to exploit this vulnerability and then convince a user
    to view the website. 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 by getting them to click a link
    in an email or instant message that takes users to the
    attacker's website, or by opening an attachment sent
    through email. In a file-sharing attack scenario, an
    attacker could provide a specially crafted document file
    designed to exploit this vulnerability and then convince
    a user to open the document file.The security update
    addresses the vulnerability by correcting how Windows
    Uniscribe handles objects in memory. (CVE-2017-8696)");

"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in
    Microsoft Office software when it fails to properly
    handle objects in memory. An attacker who successfully
    exploited the vulnerability could use a specially
    crafted file to perform actions in the security context
    of the current user. For example, the file could then
    take actions on behalf of the logged-on user with the
    same permissions as the current user. Exploitation of
    this vulnerability requires that a user open a specially
    crafted file with an affected version of Microsoft
    Office software. In an email attack scenario, an
    attacker could exploit the vulnerability by sending the
    specially crafted file to the user and convincing the
    user to open the file. In a web-based attack scenario,
    an attacker could host a website (or leverage a
    compromised website that accepts or hosts user-provided
    content) that contains a specially crafted file that is
    designed to exploit the vulnerability. However, an
    attacker would have no way to force the user to visit
    the website. Instead, an attacker would have to convince
    the user to click a link, typically by way of an
    enticement in an email or Instant Messenger message, and
    then convince the user to open the specially crafted
    file. The security update addresses the vulnerability by
    correcting how Microsoft Office handles files in memory.
    (CVE-2017-8631)

  - 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. 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. There are multiple ways an
    attacker could exploit this vulnerability. In a web-
    based attack scenario, an attacker could host a
    specially crafted website that is designed to exploit
    this vulnerability and then convince a user to view the
    website. 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 by getting them to click a link in an email
    message or in an Instant Messenger message that takes
    users to the attacker's website, or by opening an
    attachment sent through email. In a file sharing attack
    scenario, an attacker could provide a specially crafted
    document file that is designed to exploit this
    vulnerability, and then convince a user to open the
    document file. The security update addresses the
    vulnerabilities by correcting how the Windows font
    library handles embedded fonts. (CVE-2017-8682)

  - An information disclosure vulnerability exists when
    Windows Uniscribe 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 update addresses the vulnerability by correcting how
    Windows Uniscribe handles objects in memory.
    (CVE-2017-8695)

  - A remote code execution vulnerability exists due to the
    way Windows Uniscribe handles objects in memory. 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.
    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. There are
    multiple ways an attacker could exploit this
    vulnerability: In a web-based attack scenario, an
    attacker could host a specially crafted website designed
    to exploit this vulnerability and then convince a user
    to view the website. 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 by getting them to click a link
    in an email or instant message that takes users to the
    attacker's website, or by opening an attachment sent
    through email. In a file-sharing attack scenario, an
    attacker could provide a specially crafted document file
    designed to exploit this vulnerability and then convince
    a user to open the document file.The security update
    addresses the vulnerability by correcting how Windows
    Uniscribe handles objects in memory. (CVE-2017-8696)

  - A remote code execution vulnerability exists in
    Microsoft Office software 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. 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.
    Exploitation of the vulnerability requires that a user
    open a specially crafted file with an affected version
    of Microsoft Office software. In an email attack
    scenario, an attacker could exploit the vulnerability by
    sending the specially crafted file to the user and
    convincing the user to open the file. In a web-based
    attack scenario, an attacker could host a website (or
    leverage a compromised website that accepts or hosts
    user-provided content) that contains a specially crafted
    file designed to exploit the vulnerability. An attacker
    would have no way to force users to visit the website.
    Instead, an attacker would have to convince users to
    click a link, typically by way of an enticement in an
    email or instant message, and then convince them to open
    the specially crafted file. Note that the Preview Pane
    is not an attack vector for this vulnerability. The
    security update addresses the vulnerability by
    correcting how Office handles objects in memory.
    (CVE-2017-8742)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
    handles objects in memory, allowing an attacker to
    retrieve information from a targeted system. By itself,
    the information disclosure does not allow arbitrary code
    execution; however, it could allow arbitrary code to be
    run if the attacker uses it in combination with another
    vulnerability. To exploit this vulnerability, an
    attacker would have to log on to an affected system and
    run a specially crafted application. Note that where the
    severity is indicated as Critical in the Affected
    Products table, the Preview Pane is an attack vector for
    this vulnerability. The security update addresses the
    vulnerability by correcting how GDI handles memory
    addresses. (CVE-2017-8676)");
