It doesn't look like it.  They seem to have addressed the vulnerability as 
it applies to Safari, but not the underlying vulnerability.  If I send you 
an email, with a zip attachment (naming and extension is irrelevant), and I 
can get you to attempt to open the attachment (fairly trivial with many 
users), I can execute abitrary code on your machine.  The only 
"restriction" is that, if I attempt to execute code that requires admin 
privileges, I'd have to convince you to type in your password (again, 
fairly trivial for most users.)

So, Apple hasn't fully addressed this problem yet.  (Trust me, I've tested 
it.)  If you are responsible for Macs and you haven't read this yet, you 
need to:

if you're using a Mac!)
