Moin moin Bugtraq readers,

 Bill Paul and I have discovered that LoginWindow.app doesn't clear
 credentials after a user is authenticated.
This has already been discovered in 2004. While the author only looks
at swap files, it is obvious that this is the same bug.

Thanks for the heads up. It's very possible that this is the same bug
but obviously we found it in a different context. It surely seems like
it may be the original that Apple would not discuss with us.

The bug number it was duped against was over 2 million bugs prior. Does
that sound like Apple knew about this for nearly _4_ years (!) and
didn't do anything about it?

That's seriously pathetic if it's actually that case!

I reported it a little while after mailing bugtraq, was
given bug ID #3728773 which was marked as a duplicate of
#3711425 (both after your duplicate of #3250780).
Keep in mind that the increment of millions probably
includes all kinds of automated bug submissions. 

As an aside to grabbing secrets from sleeping machines,
OS X's "secure virtual memory" will encrypt the hibernate
image (good) but then seems to store the key in a nvram
variable.  So that'd be another avenue of attack I guess.
