That was quick. I'm a fan of full discosure but releasing a proof-of-concept code is not a good idea at all. It's just running after trouble for a bit of publicity.
Some times the only way to get a patch released is to publish a proof of concept.

Having said that, personaly, I do not believe in full disclosure. At least to the whole world. Although I do believe in the nead to know..........................Unless there is a clear and present threat. Then it would seem to me, to be every one for there self.
