Although it doesn't apply to this worm really, even if BIND is not run as root, it usually starts that way, so if you could exploit this hole, you could plant a "bomb" that would effectively root the box the next time BIND was run as root (such as a restart), which could then be provoked with any number of DoS attacks...

But not running BIND as root is certainly the first step. What we need is a clean-slate, audited-code DNS implementation that is configuration-file compatible with BIND -- That would certainly make migration easier for the rest of the world, and maybe we'd get away from these BIND-related nasties for good.
