Actually Apple has patched the current portable OpenSSH vulnerability with 10.2.8 <http://archives:firstname.lastname@example.org/mhonarc/security-announce/msg00035.html> which means that no G3 or G4 Mac OS X is vulnerable to it (I don't know about the G5 and if such a patch was rolled into 10.2.7). Given the recent news about it, I find it hard to state that Apple was ever one "their tuckus" about this patch. ;)
Note that Apple has pulled the updater because some users are losing their internet connection after running it. I didn't have any problems but I imagine you can check it tomorrow.
