"The remote Windows host is missing security update 4530692
or cumulative update 4530734. It is, therefore, affected by
multiple vulnerabilities :

  - A remote code execution vulnerability exists when
    Microsoft Windows OLE fails to properly validate user
    input. An attacker could exploit the vulnerability to
    execute malicious code.  (CVE-2019-1484)

  - 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
    requests. An attacker who successfully exploited this
    vulnerability could cause the RDP service on the target
    system to stop responding.  (CVE-2019-1453)

  - 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-2019-1474)

  - 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-2019-1468)

  - 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-2019-1465, CVE-2019-1466, CVE-2019-1467)

  - An information disclosure vulnerability exists when the
    win32k component improperly provides kernel information.
    An attacker who successfully exploited the vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2019-1469)

  - 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-2019-1458)

  - 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-2019-1470)

  - A security feature bypass vulnerability exists when
    Microsoft Defender improperly handles specific buffers.
    An attacker could exploit the vulnerability to trigger
    warnings and false positives when no threat is present.
    (CVE-2019-1488)

  - An elevation of privilege vulnerability exists when
    Windows improperly handles COM object creation. An
    attacker who successfully exploited the vulnerability
    could run arbitrary code with elevated privileges.
    (CVE-2019-1478)

  - 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-2019-1485)");
