iOS 6.1.3 released - Apple fixes iPhone/iPad passcode-bypass security loophole

Filed Under: Apple, Featured, iOS, Vulnerability

iPhone unlockedApple has just released iOS 6.1.3, an operating system update for iPhones and iPads that is said to fix a high profile (but probably not widely abused) flaw that could potentially allow someone to bypass your device's lock screen.

As Naked Security described last month, a video was posted on YouTube showing how nimble-fingered mischief-makers could gain access to some of the data on your iPhone or iPad by following a sequence of swipes, keypresses and even making a phoney emergency call.

The update weighs in at 18.2 MB, and can be downloaded "over-the-air" via Settings / General / Softare Update...

iOS 6.1.3 is also said to include Maps updates for Japan. It's hard to tell if Apple has included other security fixes in this release, as - at the time of writing - the company's security knowledgebase page contains no details of the security-related content in this update.

I hope you have better luck clicking on that link than I did.

Nevertheless, you have to be grateful that Apple has now fixed this security loophole. At least Apple iPhone and iPad devices are typically running an up-to-date version of their operating system.

That's not something you can so easily say about Android phones which often are way out of date, leaving the door open for exploits.

    28.5MB for me on an iphone 4s - not deployed on iPad yet

    It may be judicious to wait and see how this update affects others.
    I updated last night and the phone locked up on the first two phone calls I made today. I had to reboot the phone before I could do anything else.
    May be a coincidence, may be a symptom of a bug. Too early to tell yet.

  3. Thanks - we've written about the (returning!) flaw here:

    Worked for me without an apparent hitch - update and that link worked.
