That doesn't explain anything about how it works though.
Anybody could submit some unreadable C code that finishes up with setuid(0) and exec("/bin/sh") - it isn't interesting without an explanation of what it's doing.
Well, that's a different question. A fully fledged analysis of this exploit would certainly be interesting.
But it's an 0day, I think it's more important to patch vulnerable servers first. And I don't see what's stopping anyone from submitting an analysis of this a few days later.
