Security Updates for Windows Server 2008 (March 2018)

high Nessus Plugin ID 108300

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists when Windows Remote Assistance incorrectly processes XML External Entities (XXE). An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2018-0878)

- An information disclosure vulnerability exists when Internet Explorer improperly handles objects in memory.
An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2018-0929)

- A remote code execution vulnerability exists when Windows Shell does not properly validate file copy destinations. 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-2018-0883)


- An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory.
(CVE-2018-0811, CVE-2018-0813, CVE-2018-0814)

- A denial of service vulnerability exists when Microsoft Hyper-V Network Switch on a host server fails to properly validate input from a privileged user on a guest operating system. An attacker who successfully exploited the vulnerability could cause the host server to crash. (CVE-2018-0885)

- An information disclosure vulnerability exists in the Windows kernel that could allow an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (ASLR) bypass. An attacker who successfully exploited the vulnerability could retrieve the memory address of a kernel object. (CVE-2018-0894, CVE-2018-0895, CVE-2018-0896, CVE-2018-0897, CVE-2018-0898, CVE-2018-0899, CVE-2018-0900, CVE-2018-0901, CVE-2018-0904)

- An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2018-0868)

- A remote code execution vulnerability exists in the Credential Security Support Provider protocol (CredSSP).
An attacker who successfully exploited this vulnerability could relay user credentials and use them to execute code on the target system. CredSSP is an authentication provider which processes authentication requests for other applications; any application which depends on CredSSP for authentication may be vulnerable to this type of attack. As an example of how an attacker would exploit this vulnerability against Remote Desktop Protocol, the attacker would need to run a specially crafted application and perform a man-in-the-middle attack against a Remote Desktop Protocol session. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting how Credential Security Support Provider protocol (CredSSP) validates requests during the authentication process. To be fully protected against this vulnerability users must enable Group Policy settings on their systems and update their Remote Desktop clients. The Group Policy settings are disabled by default to prevent connectivity problems and users must follow the instructions documented HERE to be fully protected. (CVE-2018-0886)

- An elevation of privilege vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles 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-2018-0815, CVE-2018-0816, CVE-2018-0817)

- An information disclosure vulnerability exists when Windows Hyper-V on a host operating system fails to properly validate input from an authenticated user on a guest operating system. (CVE-2018-0888)
