Bug description:
tl;dr; Unity doesn't emit the ActiveChanged signal when the screen is
locked/unlocked
Long version:
unity-settings-daemon's automount plugin has code to detect whether
the screen is locked or not before automatically mounting a volume.
This prevents someone from inserting a USB thumb drive when the screen
is locked and exploiting a possible nautilus thumbnailer
vulnerability. (See bug #714958 for original implementation details.)
In Ubuntu 14.04, this code no longer works. Inserting a USB thumb
drive while the screen is locked results in a Nautilus window opening
underneath the lock screen, and the contents of the USB thumb drive
being read.
Since the screen lock got switched to Unity in Ubuntu 14.04, Unity no
longer emits the org.gnome.ScreenSaver ActiveChanged signal when the
screen gets locked or unlocked.
To test:
1- in terminal, type:
dbus-monitor
"type='signal',sender='org.gnome.ScreenSaver',interface='org.gnome.ScreenSaver'"
2- Lock the screen
3- Unlock the screen
4- Notice that no signal was received
