[lug] Shellshock exploit is worse

Please correct me if I'm wrong, but I think the shellshock exploit is much
worse than is being discussed (openly).

Consider this:

$ export cat='() { echo uh-oh; }'
$ python -c 'import os; os.system("cat")'

The fix being promoted does not change this behavior.

Python is probably the worst, because it always uses bash -c, but other
have this problem with only a slight variation:

$ ruby -e 'exec "cat *"'

Maybe I'm missing something.  I sure hope I am.
