KB4338814: Windows 10 Version 1607 and Windows Server 2016 July 2018 Security Update

High Nessus Plugin ID 110980

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4338814.
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)

- 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-2018-8290)

- 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 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-2018-8275)

- 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 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 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)

- 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 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.
(CVE-2018-8356)
