Vulnerability description

Microsoft Windows Server Service could allow a remote attacker to execute arbitrary code on the system, caused by a vulnerability in the Remote Procedure Call (RPC) service. By sending specially-crafted RPC requests to a vulnerable system, a remote attacker could exploit this vulnerability to execute arbitrary code and gain complete control over the affected system.

For Windows Vista and Windows Server 2008 the attacker must be an authenticated user with access to the target network in order to exploit this vulnerability.
