IHS Iran Hackers Sabotage Public advisory
by : c0d3r "Kaveh Razavi"  c0d3r@ihsteam.com
********************************************

well yesterday a guy found a simple user overflow in PlatinumFTPserver vr
: 1.0.18 and prior.
I downloaded the package at :
http://www.roboshareware.com/products/PlatinumFTPserver.exe
and started to disassemble the vulnerability . He was written a DoS .
PlantiumFTP has got a good error controlling system . so eip overwrite is
not easy .
but I found another vulnerability when I was fuzzing .
the server is also vulnerable to USER format string attack .
here is the result :
---------------------------------------
