Upstream patch
This issue has been classified as low impact because of the following reason(s): In order to exploit this issue, the attacker needs to - have an account on the target machine, or otherwise be able to start an app listening for key events. - have physical access to the machine to hotplug the keyboard or some other device. - be logged in at the time, but vt-switch away without the screen lock being activated. - In order to capture passwords etc, the other-use needs to have a short enough password or the other user doesn't do anything else, otherwise the events will overrun the buffer and you only get a fraction of them Created xorg-x11-server tracking bugs for this issue Affects: fedora-all [bug 952949] Upstream patch: http://cgit.freedesktop.org/xorg/xserver/commit/?id=6ca03b9161d33b1d2b55a3a1a913cf88deb2343f xorg-x11-server-1.13.3-3.fc18 has been pushed to the Fedora 18 stable repository.
