* Initialize the interpreter with Tk, safely. This removes
|
2661 |
* all the Tk commands that are unsafe.
|
2662 |
*
|
2663 |
* Rationale:
|
2664 |
*
|
2665 |
* - Toplevel and menu are unsafe because they can be used to cover
|
2666 |
* the entire screen and to steal input from the user.
|
2667 |
* - Continuous ringing of the bell is a nuisance.
|
2668 |
* - Cannot allow access to the clipboard because a malicious script
|
2669 |
* can replace the contents with the string "rm -r *" and lead to
|
2670 |
* surprises when the contents of the clipboard are pasted. We do
|
2671 |
* not currently hide the selection command.. Should we?
|
2672 |
* - Cannot allow send because it can be used to cause unsafe
|
2673 |
* interpreters to execute commands. The tk command recreates the
|
2674 |
* send command, so that too must be hidden.
|
2675 |
* - Focus can be used to grab the focus away from another window,
|
2676 |
* in effect stealing user input. Cannot allow that.
|
2677 |
* NOTE: We currently do *not* hide focus as it would make it
|
2678 |
* impossible to provide keyboard input to Tk in a safe interpreter.
|
2679 |
* - Grab can be used to block the user from using any other apps
|
2680 |
* on the screen.
|
2681 |
* - Tkwait can block the containing process forever. Use bindings,
|
2682 |
* fileevents and split the protocol into before-the-wait and
|
2683 |
* after-the-wait parts. More work but necessary.
|
2684 |
* - Wm is unsafe because (if toplevels are allowed, in the future)
|
2685 |
* it can be used to remove decorations, move windows around, cover
|
2686 |
* the entire screen etc etc.
|
2687 |
*
|
2688 |
* Current risks:
|
2689 |
*
|
2690 |
* - No CPU time limit, no memory allocation limits, no color limits.
|
2691 |
*
|
2692 |
* The actual code called is the same as Tk_Init but Tcl_IsSafe()
|
2693 |
* is checked at several places to differentiate the two initialisations.
