Thanks for the continued discussion on this issue.

It seems like, generally, fixing this vulnerability is getting a green light.

I wouldn't mind re-working the patch for this bug if I knew the
consensus on the preferred implementation. As I mentioned previously,
I'm new here, so how do I go about soliciting "votes" (or otherwise)
the preferred approach so that I may move forward.

Thanks!

Steve
