description |
The Guest Account and its associated chroot (/tmp/guest-home-XXXXX) is created/destroyed each time it is selected/deselected on the list instead of being created on login.
A user can easily DOS a system from the login screen with up/down arrows.
TEST CASE:
1. Press Down to select 'Guest Account'
-> Switch to a console and verify that a directory named /tmp/guest-home.XXXXX exists
2. Switch back to lightdm
3. Quickly press Up/Down for a few seconds to switch between the Guest Account and another entry
-> Switch to a console and count the number of ck-history process
$ pgrep ck-history|grep wc -l
The number increase really quickly to the point the system becomes unusable.
