The remote Windows host is missing security update 4338823 or cumulative update 4338818. It is, therefore, affected by multiple vulnerabilities :

  - An elevation of privilege vulnerability exists in .NET     Framework which could allow an attacker to elevate their     privilege level.  (CVE-2018-8202)

  - 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-2018-8242, CVE-2018-8296)

  - A denial of service vulnerability exists in Windows     Domain Name System (DNS) DNSAPI.dll when it fails to     properly handle DNS responses. An attacker who     successfully exploited the vulnerability could cause a     system to stop responding. Note that the denial of     service condition would not allow an attacker to execute     code or to elevate user privileges. However, the denial     of service condition could prevent authorized users from     using system resources.  (CVE-2018-8304)

  - A denial of service vulnerability exists when Windows     improperly handles objects in memory. An attacker who     successfully exploited the vulnerability could cause a     target system to stop responding.  (CVE-2018-8309)

  - An elevation of privilege vulnerability exists in     Windows when the Windows kernel-mode driver 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-2018-8282)

  - A denial of service vulnerability exists when Windows     improperly handles File Transfer Protocol (FTP)     connections. An attacker who successfully exploited the     vulnerability could cause a target system to stop     responding.  (CVE-2018-8206)

  - A security feature bypass vulnerability exists when     Microsoft Internet Explorer improperly handles requests     involving UNC resources. An attacker who successfully     exploited the vulnerability could force the browser to     load data that would otherwise be restricted.
    (CVE-2018-0949)

  - 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-2018-8308)

  - A security feature bypass vulnerability exists when     Microsoft WordPad improperly handles embedded OLE     objects. An attacker who successfully exploited the     vulnerability could bypass content blocking. In a file-     sharing attack scenario, an attacker could provide a     specially crafted document file designed to exploit the     vulnerability, and then convince a user to open the     document file. The security update addresses the     vulnerability by correcting how Microsoft WordPad     handles input. (CVE-2018-8307)

  - A Remote Code Execution vulnerability exists in .NET     software when the software fails to check the source     markup of a file. An attacker who successfully exploited     the vulnerability could run arbitrary code in the     context of the current user. If the current user is     logged on with administrative user rights, an attacker     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-2018-8260)

  - A remote code execution vulnerability exists in the way     the scripting engine handles objects in memory in     Microsoft browsers. 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-2018-8287, CVE-2018-8288, CVE-2018-8291)

  - A remote code execution vulnerability exists when the     Microsoft .NET Framework fails to validate input     properly. An attacker who successfully exploited this     vulnerability could take control of an affected system.
    An attacker could then install programs; view, change,     or delete data; or create new accounts with full user     rights. Users whose accounts are configured to have     fewer user rights on the system could be less impacted     than users who operate with administrative user rights.
    (CVE-2018-8284)

  - An elevation of privilege vulnerability exists when     Windows fails a check, allowing a sandbox escape. An     attacker who successfully exploited the vulnerability     could use the sandbox escape to elevate privileges on an     affected system. This vulnerability by itself does not     allow arbitrary code execution. However, the     vulnerability could allow arbitrary code to run if an     attacker uses it in combination with another     vulnerability, such as a remote code execution     vulnerability or another elevation of privilege     vulnerability, that can leverage the elevated privileges     when code execution is attempted. The security update     addresses the vulnerability by correcting how Windows     file picker handles paths. (CVE-2018-8314)

  - A security feature bypass vulnerability exists when     Microsoft .NET Framework components do not correctly     validate certificates. An attacker could present expired     certificates when challenged. The security update     addresses the vulnerability by ensuring that .NET     Framework components correctly validate certificates.
