Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (3057839)

This security update resolves vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

This security update is rated Important for all supported releases of Windows. For more information, see the Affected Software section.

The security update addresses the vulnerabilities by correcting how the Windows kernel-mode driver handles objects in memory and validates user input. For more information about the vulnerabilities, see the Vulnerability Information section.
