Description
The translate_hierarchy_event function in x11/clutter-device-manager-xi2.c in Clutter, when resuming the system, does not properly handle XIQueryDevice errors when a device has "disappeared," which causes the gnome-shell to crash and allows physically proximate attackers to access the previous gnome-shell session via unspecified vectors.
