Thanks for your inquiry.  As Louis has already hinted at, per standard
industry process we provide vendors (those who package or ship Samba)
with the patches 10 days before the release.  This is to provide them
with the opportunity to backport and package 

This is detailed here, hidden away in point 9:

Samba, as an open source project, publishes source code and an advisory
at the same time.  It would be pointless to hide details in the code
only, it would only make it harder for administrators, but not
determined attackers, to understand the issue.  The bug is opened up
soon after the release also.

The pre-announcment here is to give organisations that require the
scheduling of a maintaince window and the invocation of a change
control process a fighting chance to patch as soon as we release.

We include these minimal details to ensure folks can determine they
need to pay attention (or not), and to aid that internal organisational

I hope this clarifies things,
