Updates: Mac OS X 2011-002, Safari 5.0.5, iOS 4.3.2

Apple has released several security updates which patch vulnerabilities in the way Mac OS X and iOS handle certificate trust. This comes off the back of the recent Comodo hack in which several fraudulent – yet valid – SSL certificates were created for a number of prominent websites, rendering users vulnerable to potential man-in-the-middle attacks. These updates (2011-002 and iOS 4.3.2/4.2.7) improve the way certificate verification is performed in OSX and iOS. The Safari 5.0.5 update patches two critical bugs which could result in remote code execution.

In other news: Updates to Safari in Mac OS X 10.7 “Lion” have shown that the browser will bring support for the new Do-Not-Track functionality, intended to give users the ability to opt-out from tracking by Third Party tracking and ad companies. Whether or not this functionality will be fully respected by third parties remains to be seen. Lastly, a tethered jailbreak for iOS 4.3.2 has already been released.
