** Description changed:
Binary package hint: xkeyboard-config
After using to a TTY and returning to X, some or all of the input
performed in the TTY gets sent to X. This is especially bad as newlines
are sent as well, so a user with an IM/IRC entry focused, or any other
form, will have data sent from their TTY session to everyone watching,
potentially including login passwords.
+ Additionally, both in Compiz and Metacity, if the cursor was over a
+ window before the TTY switch, returning to X puts that window in "Move"
+ mode (normally triggered by holding Alt+LeftClick on a window), and
+ seems to requires escaping from this mode before the input appears.
+
Case 1:
1. Put your cursor over a non-maximized window.
2. Press Ctrl+Alt+F1 to go to TTY1.
3. Log-in.
4. Press Alt+F7 to return.
What happens:
- 1. At least in Compiz, the window is in "Move" mode, so mouse movement moves
the window. You must click to get out of this mode.
+ 1. The window is in "Move" mode, so mouse movement moves the window. You must
click to get out of this mode.
2. The help will be invoked of whatever application handled it, presumably
because you pressed F1 to use TTY1.
What should happen:
You should be return to X in the state you left it, and no input involved in
going to/from, or using the TTY, should later make it to X
Case 2:
1. Open a text editor.
2. Press Ctrl+Alt+F2 to go to TTY2
3. Type your username and press enter.
4. Press Alt+F7 to return.
What happens:
After clicking or otherwise exiting from "move" mode, the username is echoed
in the text editor.
What should happen:
See first case.
After Case 2, try going back to TTY2 and typing your password (or a fake
password, for safety), and returning. A section of the end of your
password is sent to X after returning.
