Well, I think that the problem is that too many people arent taught proper
programming to begin with..  Almost every hole that has come out in the last
2 or 3 years is because people that wrote programs assume that all data is
good..  

This hole that was mentioned was a prime example of that..  All data is valid,
so dont check for size..  If programmers start assuming that all data is
invalid, until proven valid, then security will be a lot easier to manage..

The idea of 'error checking' implies that you check for errors, not checking
for validity..

Just my opinion..
