Unpatched iPhones/iPads secure connections not so secure | Naked Security.

Yesterday I wrote about Apple’s latest fixes for iWork and iOS and encouraged folks to update. Now that more information is available it is clearly critical that all users update as soon as possible, unless they only use their device for telephone calls.

The flaws in iOS 4.3.4, 4.2.9 and 5.0b3 and lower are a lot more serious than Apple’s description of their fix: “This issue is addressed through improved validation of X.509 certificate chains.”

Do not do any e-commerce or banking transactions until you upgrade.
