Ditto as my message in response to SF-LOC.

This is what I am talking about. You are merging these two simply
because they have the same problem and can be exploited the same way
but they clearly share no code. You would run into the same problem
with things like system() calls in applications or metacharacters of CGI
programs while opening files. They are so common and you can exploits pretty
much each one in the same way you want to merge them. But they are each a
different vulnerability. I would vote to SPLIT these two.
