The remote Windows host is missing security update 4103721.
It is, therefore, affected by multiple vulnerabilities :

  - A security feature bypass vulnerability exists in .Net     Framework which could allow an attacker to bypass Device     Guard. An attacker who successfully exploited this     vulnerability could circumvent a User Mode Code     Integrity (UMCI) policy on the machine.  (CVE-2018-1039)

  - A remote code execution vulnerability exists in the way     that Microsoft browsers access objects in memory. The     vulnerability could corrupt memory in a way that could     allow an attacker to 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-2018-8178)

  - A remote code execution vulnerability exists in     Microsoft COM for Windows when it fails to     properly handle serialized objects. An attacker who     successfully exploited the vulnerability could use a     specially crafted file or script to perform actions. In     an email attack scenario, an attacker could exploit the     vulnerability by sending the specially crafted file to     the user and convincing the user to open the file.
    (CVE-2018-0824)

  - A remote code execution vulnerability exists when     Windows Hyper-V on a host server fails to properly     validate vSMB packet data. An attacker who successfully     exploited these vulnerabilities could execute arbitrary     code on a target operating system. To exploit these     vulnerabilities, an attacker running inside a virtual     machine could run a specially crafted application that     could cause the Hyper-V host operating system to execute     arbitrary code. The update addresses the vulnerabilities     by correcting how Windows Hyper-V validates vSMB packet     data. (CVE-2018-0961)

  - An information disclosure vulnerability exists when     affected Microsoft browsers improperly handle objects in     memory. An attacker who successfully exploited this     vulnerability could obtain information to further     compromise the users system.  (CVE-2018-1025)

  - 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-2018-0955, CVE-2018-8114, CVE-2018-8122)

An attacker who successfully exploited     the vulnerability could gain the same user rights as the     current user.  (CVE-2018-8174)

  - 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-2018-0943, CVE-2018-8130,     CVE-2018-8133)

  - A security feature bypass vulnerability exists when     Microsoft Edge improperly handles requests of different     origins. The vulnerability allows Microsoft Edge 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-2018-8112)

  - A denial of service vulnerability exists when .NET and     .NET Core improperly process XML documents. An attacker     who successfully exploited this vulnerability could     cause a denial of service against a .NET application. A     remote unauthenticated attacker could exploit this     vulnerability by issuing specially crafted requests to a     .NET (or .NET core) application. The update addresses     the vulnerability by correcting how .NET and .NET Core     applications handle XML document processing.
    (CVE-2018-0765)

  - 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-2018-8897)
