"The remote Windows host is missing security update 4512508.
It is, therefore, affected by multiple vulnerabilities :

  - An elevation of privilege vulnerability exists in the
    way that the Windows kernel image handles objects in
    memory. An attacker who successfully exploited the
    vulnerability could execute code with elevated
    permissions.  (CVE-2019-1190)

  - An elevation of privilege vulnerability exists when
    Windows improperly handles calls to Advanced Local
    Procedure Call (ALPC). An attacker who successfully
    exploited this vulnerability could run arbitrary code in
    the security context of the local system. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2019-1162)

  - A security feature bypass vulnerability exists when
    Microsoft browsers improperly handle requests of
    different origins. The vulnerability allows Microsoft
    browsers 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-2019-1192)

  - 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-2019-1133, CVE-2019-1194)

  - A denial of service vulnerability exists when the
    XmlLite runtime (XmlLite.dll) improperly parses XML
    input. An attacker who successfully exploited this
    vulnerability could cause a denial of service against an
    XML application. A remote unauthenticated attacker could
    exploit this vulnerability by issuing specially crafted
    requests to an XML application. The update addresses the
    vulnerability by correcting how the XmlLite runtime
    parses XML input. (CVE-2019-1187)

  - An elevation of privilege vulnerability exists when
    DirectX improperly handles 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-2019-1176)

  - An information disclosure vulnerability exists when the
    Windows RDP server improperly discloses the contents of
    its memory. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the system.  (CVE-2019-1224, CVE-2019-1225)

  - An elevation of privilege vulnerability exists when
    reparse points are created by sandboxed processes
    allowing sandbox escape. An attacker who successfully
    exploited the vulnerability could use the sandbox escape
    to elevate privileges on an affected system.
    (CVE-2019-1170)

  - A remote code execution vulnerability exists when the
    Windows Jet Database Engine improperly handles objects
    in memory. An attacker who successfully exploited this
    vulnerability could execute arbitrary code on a victim
    system. An attacker could exploit this vulnerability by
    enticing a victim to open a specially crafted file. The
    update addresses the vulnerability by correcting the way
    the Windows Jet Database Engine handles objects in
    memory. (CVE-2019-1146, CVE-2019-1147, CVE-2019-1155,
    CVE-2019-1156, CVE-2019-1157)

  - A denial of service vulnerability exists in the HTTP/2
    protocol stack (HTTP.sys) when HTTP.sys improperly
    parses specially crafted HTTP/2 requests. An attacker
    who successfully exploited the vulnerability could
    create a denial of service condition, causing the target
    system to become unresponsive.  (CVE-2019-9511,
    CVE-2019-9512, CVE-2019-9513, CVE-2019-9514,
    CVE-2019-9518)

  - <h1>Executive Summary</h1> Microsoft is aware of the
    Bluetooth BR/EDR (basic rate/enhanced data rate, known
    as &quot;Bluetooth Classic&quot;) key negotiation
    vulnerability that exists at the hardware specification
    level of any BR/EDR Bluetooth device. An attacker could
    potentially be able to negotiate the offered key length
    down to 1 byte of entropy, from a maximum of 16 bytes.
    (CVE-2019-9506)

  - A denial of service vulnerability exists in Remote
    Desktop Protocol (RDP) when an attacker connects to the
    target system using RDP and sends specially crafted

    vulnerability could cause the RDP service on the target
    system to stop responding.  (CVE-2019-1223)

  - 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-2019-1227)

  - An elevation of privilege vulnerability exists in the
    way that the PsmServiceExtHost.dll handles objects in

  - A remote code execution vulnerability exists in
    Microsoft Windows that could allow remote code execution
    if a .LNK file is processed. An attacker who
    successfully exploited this vulnerability could gain the
    same user rights as the local user.  (CVE-2019-1188)

  - An elevation of privilege exists in the p2pimsvc service
    where an attacker who successfully exploited the
    vulnerability could run arbitrary code with elevated
    privileges.  (CVE-2019-1168)

    validate input from an authenticated user on a guest
    operating system.  (CVE-2019-0965)

  - An information disclosure vulnerability exists when the
    Windows Graphics component improperly handles objects in
    memory. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the users system. An authenticated attacker

    crafted application. The update addresses the
    vulnerability by correcting how the Windows Graphics
    Component handles objects in memory. (CVE-2019-1078)

  - 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

    could execute code with elevated permissions.
    (CVE-2019-1178)

  - A remote code execution vulnerability exists when the
    Windows font library improperly handles specially
    crafted embedded fonts. An attacker who successfully
    exploited the 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-2019-1144,
    CVE-2019-1145, CVE-2019-1149, CVE-2019-1150,
    CVE-2019-1151, CVE-2019-1152)

    Desktop Services formerly known as Terminal Services
    when an unauthenticated attacker connects to the target
    system using RDP and sends specially crafted requests.
    This vulnerability is pre-authentication and requires no
    user interaction. An attacker who successfully exploited
    this vulnerability could execute arbitrary code on the
    target system. An attacker could then install programs;
    view, change, or delete data; or create new accounts
