Clutter Project » Clutter : Security Vulnerabilities, CVEs,

The gesture handling code in Clutter before 1.16.2 allows physically proximate attackers to bypass the lock screen via certain (1) mouse or (2) touch gestures.

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.
