Technical Information

Brief overview of the risk:

An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
Detailed Information on the risk:

An elevation of privilege vulnerability exists in the Client/Server Run-time Subsystem (CSRSS), allowing arbitrary code to be executed in the context of another process.
