The issue involves a vulnerability involving "through the web code"
inadvertently allowing an untrusted user to remotely shut down a
Zope server by allowing the user to inject special headers into the

code like Python Scripts, DTML Methods, or Page Templates, your
Zope server is vulnerable.
knows if 2.5.1 is going to come out in time for the release.
Also add my patch to fix setuid support (not used by default) and
set our own version string to distinguish this from an "official"
Zope release.
