[Bug 357027] [NEW] clear screen after logging out from a virtual terminal

[Kaihsu Tai]

*** This bug is a security vulnerability ***

Public security bug reported:

Binary package hint: initramfs-tools

(Sorry if this is the wrong package.)

After a user has logged out from a virtual terminal (those accessible by
Ctrl-Alt-F1...F6), the screen should clear before prompting for the next
user to log in. This would prevent snooping the actions of the last
user. Similarly, the console-screen history buffer should also clear.

** Affects: initramfs-tools (Ubuntu)
     Importance: Undecided
         Status: New

** Visibility changed to: Public
