The remote Windows host is missing security update 4493450 or cumulative update 4493451. It is, therefore, affected by multiple vulnerabilities :

  - A security feature bypass vulnerability exists in     Windows which could allow an attacker to bypass Device     Guard when Windows improperly handles calls to the LUAFV     driver (luafv.sys). An attacker who successfully     exploited this vulnerability could circumvent a User     Mode Code Integrity (UMCI) policy on the machine.
    (CVE-2019-0732)

  - An information disclosure vulnerability exists when the     Terminal Services component improperly discloses the     contents of its memory. An attacker who successfully     exploited the vulnerability could obtain information to     further compromise a users system.  (CVE-2019-0839)

  - 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-2019-0842)

  - A remote code execution vulnerability exists when     Windows improperly handles objects in memory. An     attacker who successfully exploited these     vulnerabilities could take control of an affected     system.  (CVE-2019-0856)

  - An information disclosure vulnerability exists when the     Windows TCP/IP stack improperly handles fragmented IP     packets. An attacker who successfully exploited this     vulnerability could obtain information to further     compromise the users system.  (CVE-2019-0688)

  - A remote code execution vulnerability exists when the     Microsoft XML Core Services MSXML parser processes user     input. An attacker who successfully exploited the     vulnerability could run malicious code remotely to take     control of the users system.  (CVE-2019-0790,     CVE-2019-0791, CVE-2019-0792, CVE-2019-0793,     CVE-2019-0795)

  - 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-2019-0803, CVE-2019-0859)

  - 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-2019-0752, CVE-2019-0753, CVE-2019-0862)

  - 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-2019-0846, CVE-2019-0847, CVE-2019-0851,     CVE-2019-0877, CVE-2019-0879)

  - An elevation of privilege vulnerability exists when     Windows improperly handles calls to the LUAFV driver     (luafv.sys). 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-2019-0730, CVE-2019-0731, CVE-2019-0805,     CVE-2019-0836)

  - 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-2019-0802, CVE-2019-0849)

  - An information disclosure vulnerability exists when     Windows Task Scheduler improperly discloses credentials     to Windows Credential Manager. An attacker who     successfully exploited the vulnerability could obtain     information to further compromise the users system. An     attacker could then install programs; view, change, or     delete data; or create new accounts with full user     rights.  (CVE-2019-0838)

  - An information disclosure vulnerability exists when the     scripting engine does not properly handle objects in     memory. An attacker who successfully exploited the     vulnerability could obtain information to further     compromise the users system.  (CVE-2019-0835)

  - An elevation of privilege vulnerability exists when     Windows improperly handles calls to the LUAFV driver     (luafv.sys). An attacker who successfully exploited this     vulnerability could set the short name of a file with a     long name to an arbitrary short name, overriding the     file system with limited privileges.  (CVE-2019-0796)

  - 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-2019-0848)

  - 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-2019-0844)

  - An elevation of privilege vulnerability exists when the     Windows Client Server Run-Time Subsystem (CSRSS) fails     to properly handle objects in memory. 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-2019-0735)

  - A remote code execution vulnerability exists when OLE     automation improperly handles objects in memory. An     attacker who successfully exploited the vulnerability     could gain execution on the victim system.
    (CVE-2019-0794)

  - A remote code execution vulnerability exists when the     IOleCvt interface renders ASP webpage content. An     attacker who successfully exploited the vulnerability     could run malicious code remotely to take control of the     users system.  (CVE-2019-0845)

  - A tampering vulnerability exists when Microsoft browsers     do not properly validate input under specific     conditions. An attacker who exploited the vulnerability     could pass custom command line parameters.
    (CVE-2019-0764)

  - A remote code execution vulnerability exists in the way     that the Windows Graphics Device Interface (GDI) handles     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-2019-0853)
