IIS FTP LIST Stack Exhaustion DoS

This exploit forces the IIS process inetinfo.exe to throw an unhandled exception. IIS' behavior depends on the operating system version, its configuration and the system-wide debugger specified in the registry. By default, on IIS versions 5.0, 5.1 and 6 the server will automatically restart. However if a JIT debugger is configured in the target system a message box will pop up in the console and the server will not be restarted (and continues to process requests) until a user presses [OK]. On IIS version 7 by default the server will not restart. For this exploit to be successful, the FTP server must not be empty.
