Original advisory details:

 shortcuts when the screen was locked. A local attacker could possibly use
 this issue to run commands, and unlock the current session.

 Giovanni Mellini discovered that Unity could display the Dash in certain
 conditions when the screen was locked. A local attacker could possibly use
 this issue to run commands, and unlock the current session.");
