An update to iOS 7 is being pushed out by Apple, to fix a major security flaw that possibly left email and other encrypted communication open to hacking if the user was connected to an unsecured Wi-Fi network. The iOS 7.0.6 update roll out began on Friday.
iOS 7.0.6, according to Apple, ‘provides a fix for SSL connection verification’. Apple evidently found the problem to be severe enough not to wait and deliver the fix in iOS 7.1, which is due to arrive soon.
The iOS 7.0.6 update is meant for the following devices: iPhone 4 or higher, fifth-generation Apple iPod touch, and the Apple iPad 2 or higher.
A fix for the same exploit for the Apple iPhone 3GS and fourth-generation Apple iPod touch devices is being pushed via iOS 6.1.6 update.
A Wi-Fi connection is recommended to download the update, which could vary in size from 16MB to 35MB. The iOS 7.0.6 is available to download over the air for iPhone 4 or later, iPod touch (5th generation) or later, iPad 2 or later, running iOS 5 or later. You can alternatively download it via iTunes.
We strongly recommend you back up your iOS device to iCloud or with iTunes before installing any iOS updates.
The iOS 7.0.6 update comes roughly three weeks after iOS 7.0.5 was rolled out for some iOS devices in China, which required a network provisioning fix. The iOS 7.0.4 update was slightly more significant, and brought bug fixes and improvements, including a fix for an issue that caused FaceTime calls to fail for some users.
The included security update with iOS 7.0.4 also brought a fix for an issue where app and in-app purchases could have been completed with insufficient authorisation.
