What exactly would Redmond have done? My guess is that they would of patched the bug back in February when Oracle released the patch as opposed to Apple's current practice of reactively releasing patches after an outbreak or after a security researcher gets fed up and publicly announces a vulnerability. It's worrying over the years how many instances there has been of researchers submitting a vulnerability to Apple, only to have Apple do nothing, and then when the researcher publicly releases the vulnerability Apple magically has a patch for it within a few days.
We can accuse Microsoft of many things, but not taking security seriously is not one of them. Yes, there was a time were they were hopeless but they got burned too many times and changed their attitude. They're not infallible and neither is their product but their attitude towards security and the security community puts Apple to shame.
Apple dropped the ball on this one. Things like this happen, Apple is not perfect and no one expects them to be. But instead of blindly defending them we, the Mac community and their customers, should be saying to Apple, "This is not acceptable, things have got to change. Waiting till after a serious outbreak to patch a vulnerability that was vendor patched months ago is not acceptable."
Blindly defending Apple and getting into pedantic arguments over definitions, validity of numbers, etc achieves nothing. Demanding better from Apple benefits everybody.
