I both agree and disagree with this. First, I think that we do not have
the technology to create truly bug-free software. (I once worked on a
system that claimed "provably correct software", and we can discuss this
in another subject). I've seen software that contained latent bugs for
many years. A bug can be a coding error or an error in the design. And
bugs frequently show up when a system is modified for some reason. 

However, many of our systems are not designed with security in mind.
Windows 9x is an excellent example of that. However, one can design an
architecture with security being one of the design goals. By changing
the architecture we will change the attackers' strategy. But, in doing
so, we can make it more difficult for them, but they will find a way. 

The ultimate bottom line is "there will always be exploits". Just as
there is no such thing as an escape-proof prison, there is no such thing
as an attack-proof system.
