					This module exploits a vulnerability found in Ricoh DC's DL-10 SR10 FTP
				service.  By supplying a long string of data to the USER command, it is
				possible to trigger a stack-based buffer overflow, which allows remote code
				execution under the context of the user.

					Please note that in order to trigger the vulnerability, the server must
				be configured with a log file name (by default, it's disabled).
