    descriptionThe remote Windows host is missing security update 4471326 or cumulative update 4471330. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly. 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-2018-8540) - 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-2018-8595, CVE-2018-8596) - A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory.

    "The remote Windows host is missing security update 4471321.
    It is, therefore, affected by multiple vulnerabilities :
    
      - A remote code execution vulnerability exists when the
        Microsoft .NET Framework fails to validate input
        properly. 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-2018-8540)
    
      - A Denial Of Service vulnerability exists when Connected
        User Experiences and Telemetry Service fails to validate
        certain function values. An attacker who successfully
        exploited this vulnerability could deny dependent
        security feature functionality.  (CVE-2018-8612)
    
      - 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-2018-8595, CVE-2018-8596)
    
      - A remote code execution vulnerability exists in Windows
        where Microsoft text-to-speech fails to properly handle
        objects in the 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-2018-8634)
    
      - 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-2018-8631)
    
      - 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-2018-8639)
    
      - An elevation of privilege vulnerability exists when the
        Diagnostics Hub Standard Collector Service improperly
        impersonates certain file operations. An attacker who
        successfully exploited this vulnerability could gain
        elevated privileges. An attacker with unprivileged
        access to a vulnerable system could exploit this
        vulnerability. The security update addresses the
        vulnerability by ensuring the Diagnostics Hub Standard
        Collector Service properly impersonates file operations.
        (CVE-2018-8599)
    
      - 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-2018-8477)
    
      - An information disclosure vulnerability exists when
        Remote Procedure Call runtime improperly initializes
        objects in memory.  (CVE-2018-8514)
    
      - 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-2018-8617, CVE-2018-8618,
        CVE-2018-8624, CVE-2018-8629)
    
      - An elevation of privilege vulnerability exists when the
        Windows kernel 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-2018-8611)
    
      - A remote code execution vulnerability exists in the way
        that the VBScript engine handles 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-2018-8625)
    
      - A remote code execution vulnerability exists when the
        Internet Explorer VBScript execution policy does not
        properly restrict VBScript under specific conditions. An
        attacker who exploited the vulnerability could run
        arbitrary code with medium-integrity level privileges
        (the permissions of the current user).  (CVE-2018-8619)
    
      - 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-2018-8643)
    
      - A denial of service vulnerability exists when .NET
        Framework improperly handles special web requests. An
        attacker who successfully exploited this vulnerability
        could cause a denial of service against an .NET
        Framework web application. The vulnerability can be
        exploited remotely, without authentication. A remote
        unauthenticated attacker could exploit this
        vulnerability by issuing specially crafted requests to
        the .NET Framework application. The update addresses the
        vulnerability by correcting how the .NET Framework web
        application handles web requests. (CVE-2018-8517)
    
      - 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.
        (CVE-2018-8641)
    
      - A remote code execution vulnerability exists in Windows
        Domain Name System (DNS) servers when they fail to
        properly handle requests. An attacker who successfully
        exploited the vulnerability could run arbitrary code in
        the context of the Local System Account. Windows servers
        that are configured as DNS servers are at risk from this
        vulnerability.  (CVE-2018-8626)");
