I can't speak for anybody else, but the bugs found in the beta copy of Safari on Windows work on the production copy on OS X as well," he said in a posting on the Errata site. "The exploit is robust mostly thanks to the lack of any kind of advanced security features in [Mac] OS X."
I will believe it when someone else confirms it (i.e., peer review).
Remember, people have claimed a lot of bugs with OS X before that have turned out to be a lot of hot air.
Do you work for Norton by chance? Just asking because this is the most blatant nonsense I have ever seen posted about OS X. I will email you my Static IP address and challenge you to get into my mac if you want to prove your statement.
Not to say I think OSX, let alone this beta is perfect but OSX lacks advanced security? its hardened Unix it dont get much more secure than that..
