Hello, 
 
There is possible remote buffer overflow in atftpd. It has to do with length 
of filename which client sends to atftpd server. If you send filename over 
~253 bytes, it crashes with segfault. When I attach to process with gdb I 
can see it trying to run instruction from EIP 0x41414141. That cant be a 
good thing. I've tested this on debian woody. I've creating proof of concept 
exploit for it but having few troubles :) 
 
later, 
Rick Patel
