As we have with previous Windows security vulnerabilities, we are developing a new free tool to fully address and permanently cure "the DCOM problem", since Microsoft has not.
Our tool will preempt and prevent this and any next exploits of DCOM. Microsoft's patch is certainly useful (and you should definitely use it if you have not), but that's what it is: another patch to an insecure philosophy. It demonstrates that Microsoft still doesn't understand security.
