Bug description:
Binary package hint: gdm
In many environments computers are left unattended (e.g. schools,
libraries, etc) and people can launch applications which mimic the
look-and-feel of the login application (GDM) in order to get the users
username and password.
This is called login spoofing.
* http://en.wikipedia.org/wiki/Login_spoofing
Login spoofing can be prevented by using a secure attention key which is a
key combination pressed before the user login to launch the password request
dialog. This key can only be seen by the kernel, and not sniffed by any
application.
