=)  And it's now public... expect the exploits any hour now.

Not really.  Except upgrading to 3.4 and then you can turn privsep off
since the vulnerability is fixed.

Well, 3.4 looks a little better, but still problems with PAM.  I hope
a 3.4.1 fixes all of the PAM issues, but until then, 3.4 is your best
bet (you can use it without privsep if you are really concerned about
expired passwords, etc.).

In cooker, and building it for updates.  This one will be going thru
QA so the packages won't be available today for updates.
