The same question again and again

As a Zope user I prefer to know as soon as possible if Zope has security
problems like those

Perhaps the correct way will be to send the problem to the zope people and 2
weeks later then make it public

I think 2 weeks is a very correct period to solve a problem if not, I want
to try to solve the problem for myself

But I shout my mouth, sorry Andreas ;)
