"The remote Windows host is missing security update 4516044.
It is, therefore, affected by multiple vulnerabilities :

  - An elevation of privilege vulnerability exists in
    Windows Text Service Framework (TSF) when the TSF server
    process does not validate the source of input or
    commands it receives. An attacker who successfully
    exploited this vulnerability could inject commands or
    read input sent through a malicious Input Method Editor
    (IME). This only affects systems that have installed an
    IME.  (CVE-2019-1235)

  - An information disclosure exists in the Windows Common
    Log File System (CLFS) driver when it fails to properly
    handle sandbox checks. An attacker who successfully
    exploited this vulnerability could potentially read data
    outside their expected limits.  (CVE-2019-1282)

  - An information disclosure vulnerability exists when the
    Windows kernel fails to properly initialize a memory
    address. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the users system.  (CVE-2019-1274)

  - An information disclosure vulnerability exists when
    Windows Hyper-V writes uninitialized memory to disk. An
    attacker could exploit the vulnerability by reading a
    file to recover kernel memory.  (CVE-2019-1254)

  - An elevation of privilege vulnerability exists when the
    Windows Update Delivery Optimization does not properly
    enforce file share permissions. An attacker who
    successfully exploited the vulnerability could overwrite
    files that require higher privileges than what the
    attacker already has.  (CVE-2019-1289)

  - An elevation of privilege vulnerability exists when the
    .NET Framework common language runtime (CLR) allows file
    creation in arbitrary locations. An attacker who
    successfully exploited this vulnerability could write
    files to folders that require higher privileges than
    what the attacker already has.  (CVE-2019-1142)

  - An information disclosure vulnerability exists when
    DirectWrite 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 DirectWrite handles objects in memory.
    (CVE-2019-1244, CVE-2019-1245)

  - An elevation of privilege vulnerability exists in

    vulnerable to symbolic link attack. An attacker who
    successfully exploited this vulnerability could bypass
    access restrictions to add or remove files.
    (CVE-2019-1270)

  - An elevation of privilege vulnerability exists in
    Microsoft Compatibility Appraiser where a configuration
    file, with local privileges, is vulnerable to symbolic
    link and hard link attacks. An attacker who successfully
    exploited this vulnerability could run processes in an
    elevated context. An attacker could then install
    programs; view, change or delete data.  (CVE-2019-1267)

  - 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-2019-1269, CVE-2019-1272)

  - 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-2019-1280)

  - An information disclosure vulnerability exists in
    Windows when the Windows SMB Client kernel-mode driver
    fails to properly handle objects in memory. An attacker
    who successfully exploited the vulnerability could
    potentially disclose contents of System memory.
    (CVE-2019-1293)

  - 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-2019-1240, CVE-2019-1241, CVE-2019-1242,
    CVE-2019-1243, CVE-2019-1246, CVE-2019-1247,
    CVE-2019-1248, CVE-2019-1249, CVE-2019-1250)

  - 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-2019-1232)

  - 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-2019-1256, CVE-2019-1285)

  - 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-2019-1208, CVE-2019-1236)

  - An elevation of privilege vulnerability exists in the
    way that the Windows Network Connectivity Assistant
    handles objects in memory. An attacker who successfully
    exploited the vulnerability could execute code with
    elevated permissions.  (CVE-2019-1287)

  - A remote code execution vulnerability exists in the
    Windows Remote Desktop Client when a user connects to a
    malicious server. An attacker who successfully exploited
    this vulnerability could execute arbitrary code on the
    computer of the connecting client. An attacker could
    then install programs; view, change, or delete data; or
    create new accounts with full user rights.
    (CVE-2019-1290, CVE-2019-1291)

  - A security feature bypass vulnerability exists when
    Microsoft Browsers fail to validate the correct Security
    Zone of requests for specific URLs. This could allow an
    attacker to cause a user to access a URL in a less
    restricted Internet Security Zone than intended.
    (CVE-2019-1220)

  - An elevation of privilege exists when Winlogon does not
    properly handle file path information. An attacker who
    successfully exploited this vulnerability could run
    arbitrary code. An attacker could then install programs;
    view, change, or delete data; or create new accounts
    with full user rights.  (CVE-2019-1268)

  - A denial of service vulnerability exists when Microsoft
    Hyper-V on a host server fails to properly validate
    input from a privileged user on a guest operating
    system.  (CVE-2019-0928)
