(MS11-063) Vulnerability in Windows Client/Server Run-time Subsystem Could Allow Elevation of Privilege (2567680)
Severity: HIGH
CVE Identifier: CVE-2011-1967
Advisory Date: AUG 11, 2011
DESCRIPTION
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application designed to send a device event message to a higher-integrity process. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
The security update addresses the vulnerability by modifying the way that the Client/Server Run-time Subsystem (CSRSS) evaluates inter-process device event message permissions.
