Apple iOS 6.0.1 update fixes security vulnerabilities

iPhone5_deviceThe Apple iOS 6.0.1 update in the main is applicable to the iPhone 5 but is also available for other iOS devices such as the iPad Touch, and iPod Touch. A quick glance and I failed to notice any changes to Apple maps, so maybe this will come in another update?

If you use an iPhone 5 that you will notice an “updater for iPhone 5” which needs downloading first. This patches the iPhone 5 which was originally prevented from installing updates OTA. After installing the updater, you will then be asked to install the iOS 6.0.1 update.

If you don’t see this update, here is another way:
Go to – Settings > General > Software Update > Download and Install

Here are the major high-level improvements and fixes to iOS 6.0.1:

  • Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air
  • Fixes a bug where horizontal lines may be displayed across the keyboard
  • Fixes an issue that could cause camera flash to not go off
  • Improves reliability of iPhone 5 and iPod Touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks – this WPA2 issue has been intermittent along with weaker signal since iOS 6.0 was installed on my iPod Touch 4th Generation
  • Resolves an issue that prevents iPhone from using the mobile network in some instances
  • Consolidated the use Mobile Data switch for iTunes Match
  • Fixes a Passcode Lock bug that sometimes allowed access to Passbook pass details from lock screen (see Advisory below)
  • Fixes a bug affecting Exchange meetings

In addition to the above, Apple’s advisory also details the following security fixes:

  • Kernel, to address an issue where maliciously crafted or compromised iOS applications may determine addresses in the kernel
  • Passcode Lock, to address an issue where a person with physical access to the device may access Passbook passes without entering a passcode
  • Webkit, to address a bug where visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution.

My friends at Sophos have also highlighted that the previous iOS 6.0 patched 197 vulnerabilities in 41 system components. Who said Apple was not discovering exploits in its operating system? No operating system is 100% secure and never will be, even if Apple pursues a “walled garden” policy.

Safe surfing folks!
