Microsoft Remote Desktop Protocol Security Feature Bypass Vulnerability

A security feature bypass vulnerability exists in Remote Desktop Protocol (RDP) when RDP does not properly log failed logon attempts. The vulnerability could allow an attacker to bypass the audit logon security feature. The security feature bypass by itself does not allow arbitrary code execution. However an attacker could use this bypass vulnerability in conjunction with another vulnerability. The update addresses the vulnerability by correcting the way Remote Desktop Protocol handles authentication and logging.
