KB4103712: Windows 7 and Windows Server 2008 R2 May 2018 Security Update

High Nessus Plugin ID 109604

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4103712 or cumulative update 4103718. It is, therefore, affected by multiple vulnerabilities :

- 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)

- 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)

- 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-2018-8120, CVE-2018-8124, CVE-2018-8164, CVE-2018-8166)

- 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-2018-0954, CVE-2018-1022)

- 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)

- An information disclosure vulnerability exists when Chakra improperly discloses the contents of its memory, which could provide an attacker with information to further compromise the users computer or data.
(CVE-2018-8145)

- A remote code execution vulnerability exists in the way that Windows handles objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code with elevated permissions on a target system. (CVE-2018-8136)

- 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-2018-8127)

- An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8167)

- A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. (CVE-2018-0959)

- 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 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 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)

- 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-2018-8174)

- 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)
