| MS11-056 | Vulnerabilities in Windows Client/Server Run-time Subsystem Could Allow Elevation of Privilege (2507938) | Windows XP | Critical | 13-07-2011 |
Technical Information
Brief overview of the risk:
This security update resolves five privately reported vulnerabilities in the Microsoft Windows Client/Server Run-time Subsystem (CSRSS). The vulnerabilities could allow elevation of privilege if an attacker logs on to a user’s system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit the vulnerabilities.
Detailed Information on the risk:
An elevation of privilege vulnerability exists in Windows CSRSS due to the way that the CSRSS subsystem assigns memory for specific user transactions. 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.
