Security alerts aggregator Secunia Inc. rated the update as 'highly critical' and warned that Mac users are at risk of security bypass, cross-site scripting, data manipulation, data leakage, privilege escalation, denial-of-service and system access attacks.There's even mention of buffer-overflows in the OS, something Mac zealots have been mocking Microsoft about for years. Turn about is fair play, my friends...glass houses and all that.
If you're considering a Mac for security reasons, that's fair (you'll definitely not face the spyware nightmare PC users do), but don't think that a Mac relieves you of the necessity of due diligence. It can't. Nothing can.
