For the testing distribution (wheezy), this problem has been fixed in

For the unstable distribution (sid), this problem has been fixed in

the X.Org X server was vulnerable to an information disclosure flaw
related to input handling and devices hotplug.

When an X server is running but not on front (for example because of a VT
switch), a newly plugged input device would still be recognized and
handled by the X server, which would actually transmit input events to
its clients on the background.

This could allow an attacker to recover some input events not intended
for the X clients, including sensitive information.";
