Apple releases iOS 10.3.1 with bug fixes & improved security for iPhone & iPad, incl. 32-bit devices

Apple has just begun rolling out iOS 10.3.1 for iPhones and iPads. With Apple’s iOS 10.3 release we saw a lack of support for 32-bit devices, but that’s changed with today’s update. iOS 10.3.1 brings back support for 32-bit devices and is available for the iPhone 5 and 5c. Release notes for this particular update are light, only noting bug fixes and security improvements.

Today’s update follows Apple’s release of iOS 10.3.2 beta 1 last week for developers. As some readers had pointed out at the time, it appeared Apple had skipped 10.3.1 and went straight for 10.3.2. Apple’s developer site also lists 32-bit devices, like the iPhone 5 and 5c as available to receive today’s update as well.

iOS 10.3.1 includes a Wi-Fi vulnerability fix discovered by Google’s Project Zero:


Available for: iPhone 5 and later, iPad 4th generation and later, iPod touch 6th generation and later

Impact: An attacker within range may be able to execute arbitrary code on the Wi-Fi chip

Description: A stack buffer overflow was addressed through improved input validation.
