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:
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.
