KB4462941: Windows 8.1 and Windows Server 2012 R2 October 2018 Security Update

High Nessus Plugin ID 118002

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4462941 or cumulative update 4462926. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists when Internet Explorer improperly accesses 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-2018-8460, CVE-2018-8491)

- A security feature bypass vulnerability exists in DNS Global Blocklist feature. An attacker who successfully exploited this vulnerability could redirect traffic to malicious DNS endpoints. The update addresses the vulnerability by updating DNS Server Role record additions to not bypass the Global Query Blocklist.
(CVE-2018-8320)

- 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-2018-8330)

- An information disclosure vulnerability exists when DirectX improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how DirectX handles objects in memory.
(CVE-2018-8486)

- An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability. (CVE-2018-8472)

- 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-2018-8489)

- 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-2018-8453)

- An information disclosure vulnerability exists when the Windows TCP/IP stack improperly handles fragmented IP packets. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8493)

- An elevation of privilege vulnerability exists when NTFS improperly checks access. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8411)

- A remote code execution vulnerability exists when the Microsoft XML Core Services MSXML parser processes user input. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the users system. (CVE-2018-8494)

- An information disclosure vulnerability exists when Windows Media Player improperly discloses file information. Successful exploitation of the vulnerability could allow an attacker to determine the presence of files on disk. (CVE-2018-8481, CVE-2018-8482)

- A remote code execution vulnerability exists when "Windows Theme API" does not properly decompress files. 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.
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-2018-8413)

- An elevation of privilege vulnerability exists when the DirectX Graphics Kernel (DXGKRNL) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8484)

- A remote code execution vulnerability exists in the Microsoft JET Database Engine. 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-2018-8423)

- An Elevation of Privilege vulnerability exists in Filter Manager when it improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute elevated code and 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. (CVE-2018-8333)
