Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

"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)");

    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

    CVE-2017-8684)

  - A memory corruption vulnerability exists in the Windows
    Server DHCP service when an attacker sends specially
    crafted packets to a DHCP failover server. An attacker
    who successfully exploited the vulnerability could
    either run arbitrary code on the DHCP failover server or
    cause the DHCP service to become nonresponsive. To
    exploit the vulnerability, an attacker could send a
    specially crafted packet to a DHCP server. However, the
    DHCP server must be set to failover mode for the attack
    to succeed. The security update addresses the
    vulnerability by correcting how DHCP failover servers
    handle network packets. (CVE-2017-8686)

  - 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)

  - 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-2017-8692)

  - 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 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 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 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, CVE-2017-8713)

  - A remote code execution vulnerability exists in the VM
    Host Agent Service of Remote Desktop Virtual Host role
    when it fails to properly validate input from an
    authenticated user on a guest operating system. To
    exploit the vulnerability, an attacker could issue a
    specially crafted certificate on the guest operating
    system that could cause the VM host agent service on the
    host operating system to execute arbitrary code. The
    Remote Desktop Virtual Host role is not enabled by
    default. An attacker who successfully exploited the
    vulnerability could execute arbitrary code on the host
    operating system. The security update addresses the
    vulnerability by correcting how VM host agent service
    validates guest operating system user input.
    (CVE-2017-8714)

  - 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 when
    Microsoft Windows PDF Library improperly handles objects
    in memory. The vulnerability could corrupt memory in 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-2017-8728, CVE-2017-8737)

  - A remote code execution vulnerability exists in the way
    that Microsoft browser JavaScript engines render content
    when handling objects in memory. The vulnerability could

    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-2017-8675)

  - 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

    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-2017-8684)

  - A memory corruption vulnerability exists in the Windows
    Server DHCP service when an attacker sends specially
    crafted packets to a DHCP failover server. An attacker
    who successfully exploited the vulnerability could
    either run arbitrary code on the DHCP failover server or
    cause the DHCP service to become nonresponsive. To
    exploit the vulnerability, an attacker could send a
    specially crafted packet to a DHCP server. However, the
    DHCP server must be set to failover mode for the attack
    to succeed. The security update addresses the
    vulnerability by correcting how DHCP failover servers
    handle network packets. (CVE-2017-8686)

  - 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)

  - 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-2017-8692)

  - 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 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 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 when
    Windows Hyper-V on a host operating system fails to
    properly validate input from an authenticated user on a
    guest operating system. (CVE-2017-8713)

  - A remote code execution vulnerability exists in the VM
    Host Agent Service of Remote Desktop Virtual Host role
    when it fails to properly validate input from an
    authenticated user on a guest operating system. To
    exploit the vulnerability, an attacker could issue a
    specially crafted certificate on the guest operating
    system that could cause the VM host agent service on the
    host operating system to execute arbitrary code. The
    Remote Desktop Virtual Host role is not enabled by
    default. An attacker who successfully exploited the
    vulnerability could execute arbitrary code on the host
    operating system. The security update addresses the
    vulnerability by correcting how VM host agent service
    validates guest operating system user input.
    (CVE-2017-8714)

  - 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)

  - A remote code execution vulnerability exists when
    Microsoft Windows PDF Library improperly handles objects
    in memory. The vulnerability could corrupt memory in 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-2017-8728, CVE-2017-8737)

  - 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)

  - 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)

  - 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 .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)");

    descriptionThe remote Windows host is missing multiple security updates released on 2017/09/12. It is, therefore, affected by multiple vulnerabilities : - 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. To exploit the vulnerability, an attacker on a guest operating system could run a specially crafted application that could cause the Hyper-V host operating system to disclose memory information. An attacker who successfully exploited the vulnerability could gain access to information on the Hyper-V host operating system. The security update addresses the vulnerability by correcting how Hyper-V validates guest operating system user input. (CVE-2017-8707) - 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 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. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The security update addresses the vulnerability by correcting how the Windows kernel handles memory addresses. (CVE-2017-8687) - 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. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system. The update addresses the vulnerability by correcting the way in which the Windows Graphics Component handles objects in memory. (CVE-2017-8683) - 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
