iOS 10.3.1 update released to fix Wi-Fi flaw

Just one week after releasing iOS 10.3, Apple has released iOS 10.3.1, which appears to be a minor update to fix Wi-Fi security problems and other issues that have popped up since the release of iOS 10.3. 


The security note accompanying iOS 10.3.1 says simply that the fixed problem is a stack buffer overflow vulnerability that was addressed through improved input validation, and that it allows an attacker within range to execute arbitrary code on the Wi-Fi chip.

No more details about it were shared, but Gal Beniamini of Google Project Zero – the discoverer of the flaw – noted that more information about it will be provided tomorrow, and that it is not the same bug as the one he found last year in Broadcom’s Wi-Fi HardMAC SoC (system-on-a-chip) product.

iOS 10.3.1 is available for practically all iDevices out there: iPhone 5 and later, iPad 4th generation and later, iPod touch 6th generation and later. So, if you own one or more of them, it’s a good idea to start patching.
