4. Technical Description:
4.1. Details:
gtk-vnc is a VNC viewer widget for GTK. It is built using coroutines
allowing it to be completely asynchronous while remaining single
threaded. It provides a core C library, and bindings for Python
(PyGTK). It also provides a web browser plugin featuring a Gtk VNC
widget which can be embedded in a web page.
It can be used with virt-manager(1) and vinagre(1).

4.11. Security Impact:
gtk-vnc implements its own 3DES algorithm, and makes use of GnuTLS
for other usages of encryption. They are used for authentication
between VNC server and client. The server side decides the
authentication method.
If server does not have GnuTLS support, it uses 3DES to authenticate
the client. The steps are:
1) Server sends a random 16 byte challenge
2) Client encrypts the challenge with DES using the user supplied
password as a key and send back to server
3) If the response matches the expected result, the client is
authenticated. Otherwise, the server closes the connection.
If server does have GnuTLS support, then gtk-vnc uses GnuTLS
anonymous or X.509 certificate authentication as a way to
authenticate a client. Then, gtk-vnc uses the steps described
above to finish.
At connection time, the VNC server uses libz(3) function deflate to
compress data. The VNC client uses libz(3) function inflate to
decompress data.
4.12. Dependencies:
gtk-vnc uses GnuTLS to preform authentication between VNC server
and client. Also gtk-vnc depends on zlib(3).
gtk-vnc's web browser plugin depends on firefox(1).
gtk-vnc's python binding needs python(1).
gtk-vnc is Vinagre's dependency.
When virt-manager(1) is modified to use gtk-vnc, it is
virt-manager's dependency.
