  - A security feature bypass vulnerability exists in the Microsoft Chakra scripting engine that allows
    Control Flow Guard (CFG) to be bypassed, aka "Scripting Engine Security Feature Bypass Vulnerability."
    This affects Microsoft Edge, ChakraCore. (CVE-2018-8276)

The remote Windows host is missing security update 4338826.
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 when     Microsoft Edge improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way     that enables 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-2018-8125,     CVE-2018-8274, CVE-2018-8275, CVE-2018-8279)

  - 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 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 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 security feature bypass vulnerability exists in Device     Guard that could allow an attacker to inject malicious     code into a Windows PowerShell session. An attacker who     successfully exploited this vulnerability could inject     code into a trusted PowerShell process to bypass the     Device Guard Code Integrity policy on the local machine.
    (CVE-2018-8222)

  - 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 information disclosure vulnerability exists when     Microsoft Edge improperly handles objects in memory. An     attacker who successfully exploited the vulnerability     could obtain information to further compromise the users     system.  (CVE-2018-8324)

  - 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 security feature bypass vulnerability exists in the     Microsoft Chakra scripting engine that allows Control     Flow Guard (CFG) to be bypassed. By itself, the CFG     bypass vulnerability does not allow arbitrary code     execution. However, an attacker could use the CFG bypass     vulnerability in conjunction with another vulnerability,     such as a remote code execution vulnerability, to run     arbitrary code on a target system.  (CVE-2018-8276)

  - An elevation of privilege vulnerability exists in the     way that the Windows Kernel API enforces permissions. An     attacker who successfully exploited the vulnerability     could impersonate processes, interject cross-process     communication, or interrupt system functionality.
    (CVE-2018-8313)

  - 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)

  - 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-2018-8280, CVE-2018-8286,     CVE-2018-8290)

  - A security feature bypass vulnerability exists when     Microsoft .NET Framework components do not correctly     validate certificates.
