Potential printf() uses that expose vulnerabilities

In my opinion it is an interesting article if for nothing else other than the fact that it puts you to thinking of the various possibilities.

I myself code lot in C and I heavily utilize printf and don't believe that everything can possibly be taken into consideration in a real world non-academic situation. It's good to use the updated functions as the author says but not using low level string manipulation might not always be the case if you are coding in C.
