script_tag(name:"insight", value:"David Airlie and Peter Hutterer of Red Hat discovered that xorg-server, 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.
For the stable distribution (squeeze), this problem has been fixed in version 2:1.7.7-16.
For the testing distribution (wheezy), this problem has been fixed in version 2:1.12.4-6.
For the unstable distribution (sid), this problem has been fixed in version 2:1.12.4-6.
We recommend that you upgrade your xorg-server packages.");
