iOS 10.3.1 Security Update Fixes Wi-Fi Vulnerability

iOS 10 Security

In a bit of a surprise, Apple has just pushed fresh security updates for its mobile operating system to iOS 10.3.1. This update arrives just one week after Apple’s release of iOS 10.3 for the iPhone and iPad, which offered a hefty list of vulnerability fixes to over 80 security flaws.

iOS 10.3.1 is available for iPhone 5 and later, iPad 4th generation and later, and iPod touch 6th generation and later.

Apple’s security bulletin describes the vulnerability discovered by Google's Project Zero, and its fix, as follows:

iOS 10.3.1 Security Update

CVE-2017-6975 : An attacker within range may be able to execute arbitrary code on the Wi-Fi chip. A stack buffer overflow was addressed through improved input validation.

Apple’s iOS update appears to also address some problems that were caused by iOS 10.3, as mentioned by Amit Chowdhry at Forbes.

“Soon after iOS 10.3 was released, Apple had to pull it from the iPhone 5 and iPhone 5c. Fortunately, iOS 10.3.1 fixes the problem that Apple was seeing with the iPhone 5 and iPhone 5c as confirmed by AppleInsider. It is worth mentioning that the iPhone 5 and iPhone 5c were Apple’s last iPhone models to have a 32-bit processor (Apple A6 system on a chip). The iPhone 5s did not have any problems because it has a 64-bit processor.”

Apple iOS users can get the iOS 10.3.1 update by going to Settings > General > Software Updates on your device. You can also connect your iOS device to your Mac and let iTunes do the update for you.

    This update isn’t working for me over wifi. Downloads ok, but after clicking install, file verification begins but ends with error message saying I am not connected to the internet.
    Turned off wifi on my phone and update worked ok connected to cellular.
    Still can’t update iPad because it’s wifi only.

      I’m having same issue but even with wifi turned off it still won’t install.

    Here’s an issue. My phone has shut down TWICE on its own since I updated it and the screen has frozen once. I’ve had to do a soft reset twice. Be careful with this update.

    This update has completely jacked up my phone. Nothing works, textes, internet, or anything. My phone just shuts down.

    After the update on my iPad I am asked to validate from another apple device to maintain my iCloud content. I don’t have another apple device. The genius tells me that there isn’t any other way to validate, so I will have to reset and lose everything, thus losing my keychain of passwords. His solution is to write them down. Do you know of a fix for this?
