Published:

Version: 1.0

General Information

Executive Summary

This security update resolves one publicly disclosed and two privately reported vulnerabilities in the Windows kernel. A local attacker who successfully exploited these vulnerabilities could take complete control of an affected system. The vulnerabilities could not be exploited remotely or by anonymous users.

This security update is rated Important for all supported editions of Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerabilities by correcting window property validation passed during the new window creation process, correcting the manner in which system calls from multiple threads are handled, and correcting validation of parameters passed to the Windows Kernel from user mode.
