Comment(by rransom):

 Replying to [comment:3 kaner]:
 > The reason for installing this package on a torproject.org machine is
 the PlotStat.py script that is needed to plot GetTor statistics. Question
 to you: Why do you ask what the reason to install the package is? Is the
 package dangerous?

 Tk contains a code-exec backdoor (the `send` command) available to anyone
 who can connect to the X display that it is using.  Python-Tk does not
 attempt to close this backdoor.

 On a desktop system, this is not significantly worse than the ability to
 inject mouse and keyboard events to e.g. GNOME Panel and the Run
 Application dialog box.  On a server, either (a) Tk would be a security
 risk (by allowing anyone who can connect to an X display on the server to
 run arbitrary code with the privileges of the PlotStat.py process) or (b)
 Tk would not work (because there is no X display).

 Also, your script does not actually require python-tk.  See
 [ticket:4342#comment:31] for how to configure MatPlotLib properly.

 I would assume that they already know.  For example, they ship the TkCon
 program which uses the `send` command to implement a debugging tool.
 Other packages in Debian (e.g. PLplot) rely on `send`.
