2017 for Apple has mostly been about the iOS 11 — among other things talked about at WWDC 2017 — and the upcoming 10th-anniversary edition iPhone 8. Moving ahead, the company has also fixed a serious security vulnerability with the device’s WiFi which could have led to a hacker controlling your device.
Apple is rolling out its latest security update in the form of iOS update 10.3.3 for iPhone 5 and later, iPad 4th generation and later, and iPod touch 6th generation.
One of the main issues, as mentioned by Apple, could enable “an attacker within range to execute arbitrary code on the Wi-Fi chip”.
In simpler words, an attacker could’ve gained remote access to your device without you knowing and could use your device and even steal your data.
The issue was being caused due to memory corruption and was “addressed with improved memory handling”.
Other than that, the latest iOS update also fixes security vulnerabilities arising out of the operating system’s WebKit and Kernel, which could’ve led to arbitrary code execution due to a malicious web code and could also give access to apps to read the restricted memory of the device.
The issue with WiFi was arising out of the Broadcom WiFi chips being used in the devices. The same chips are also being used in Samsung, LG, Google and HTC devices.
While Apple’s fixes will be released to all its users alike, most Android users running non-Google branded devices are still dependent on their respective smartphone manufacturers to roll out an update customised to the device.
