Microsoft Security Bulletin MS10-047 - Important

Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege (981852)

Published: Tuesday, August 10, 2010

Version: 1.0

General Information

Executive Summary

This security update resolves several privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logged on locally and ran a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit these vulnerabilities. The vulnerabilities could not be exploited remotely or by anonymous users.

This security update is rated Important for Windows XP, Windows Vista, and Windows Server 2008; and Moderate for Windows 7 and Windows Server 2008 R2. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerabilities by correcting Windows kernel object initialization and validation of access control lists and by introducing additional runtime validation to the thread creation mechanism. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Recommendation. The majority of customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.

For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.

Windows Kernel Data Initialization Vulnerability - CVE-2010-1888

An elevation of privilege vulnerability exists in the Windows Kernel due to the way the kernel deals with specific thread creation attempts. 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.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-1888.

FAQ for Windows Kernel Data Initialization Vulnerability - CVE-2010-1888

What is the scope of the vulnerability?
This is an elevation of privilege vulnerability. An attacker who successfully exploited this vulnerability could execute arbitrary code and take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

What causes the vulnerability?
This vulnerability is caused by a race condition when creating specific types of threads.

What is the Windows kernel?
The Windows kernel is the core of the operating system. It provides system-level services such as device management and memory management, allocates processor time to processes, and manages error handling.

What might an attacker use the vulnerability to do?
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.

How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take complete control over an affected system.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do?
The update addresses this vulnerability by introducing additional runtime validation to the thread creation mechanism.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.

Windows Kernel Double Free Vulnerability - CVE-2010-1889

An elevation of privilege vulnerability exists in the Windows Kernel due to the way the kernel initializes objects while handling certain errors. 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.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-1889.

Mitigating Factors for Windows Kernel Double Free Vulnerability - CVE-2010-1889

Workarounds for Windows Kernel Double Free Vulnerability - CVE-2010-1889

FAQ for Windows Kernel Double Free Vulnerability - CVE-2010-1889

What causes the vulnerability?
Windows kernel does not initialize objects properly while handling certain errors.

What does the update do?
The update addresses the vulnerability by ensuring that the Windows kernel initializes objects properly while handling certain errors.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

Windows Kernel Improper Validation Vulnerability - CVE-2010-1890

A denial of service vulnerability exists in the way that the Windows kernel validates access control lists on kernel objects. An attacker could exploit the vulnerability by running a specially crafted application causing the system to become unresponsive and automatically restart.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-1890.

Mitigating Factors for Windows Kernel Improper Validation Vulnerability - CVE-2010-1890

Workarounds for Windows Kernel Improper Validation Vulnerability - CVE-2010-1890

FAQ for Windows Kernel Improper Validation Vulnerability - CVE-2010-1890

What is the scope of the vulnerability?
This is a denial of service vulnerability. An attacker who exploited this vulnerability could cause the affected system to stop responding and automatically restart. Note that the denial of service vulnerability would not allow an attacker to run code or to elevate the attacker's user rights, but it could cause the affected system to stop accepting requests.

What causes the vulnerability?
The Windows kernel does not properly validate access control lists on kernel objects.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could cause the affected system to stop responding.

What does the update do?
The update addresses this vulnerability by correcting the manner in which the Windows kernel validates access control lists applied to kernel objects.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

Update Compatibility Evaluator and Application Compatibility Toolkit

Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit.

The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
