This host is missing a critical security update according to Microsoft Bulletin MS11-004.

Successful exploitation could allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted FTP request that triggers memory corruption. Impact Level: System/Application

Run Windows Update and update the listed hotfixes or download and update mentioned hotfixes in the advisory from the below link, http://www.microsoft.com/technet/security/bulletin/ms11-004.mspx

The flaw is due to a boundary error when encoding Telnet IAC characters in a FTP response. This can be exploited without authenticating to the FTP service to cause a heap-based buffer overflow by sending an overly long, specially crafted FTP request.
