'Name' => 'Microsoft RRAS Service Overflow',

'Description'=> %q{

This module exploits a stack buffer overflow in the Windows Routing and Remote

Access Service. Since the service is hosted inside svchost.exe, a failed

exploit attempt can cause other system services to fail as well. A valid

username and password is required to exploit this flaw on Windows 2000.

When attacking XP SP1, the SMBPIPE option needs to be set to 'SRVSVC'. },
