** Description changed:
- Because of light locker being added to Xubuntu, it's now possible to
- bypass the screen lock.
+ HOW TO REPRODUCE:
+ 1. Create an user account with password.
+ 2. Login in the new account using the XFCE desktop environment.
+ 3. Lock the screen.
+ 4. Hit the Ctrl+Alt+F7 key combination.
- light-locker creates a lockscreen on VT8 - however, we can switch back
- to the original VT using keyboard commands, meaning that we have full
- access to the user's desktop.
+ EXPECTED BEHAVIOUR:
+ - The user session to be unavailable due to no password being entered.
-
- Steps:
-
- Install Xubuntu
- Create user with password
- Login as that user
- Lock screen (xflock4 or ctrl+alt+delete)
- Hit Ctrl+alt+f7
- Use the system without using a password to unlock.
+ REAL BEHAVIOUR:
+ - The session is accessible without entering its password, due to the VT8
being bypassed to the original VT using the Ctrl+Alt+F7 key combination.
