Apple released iOS 10.1 yesterday and it’s very important that if you have an iPhone (Gen 5 or later) you update your software ASAP because a very worrisome security defect was exposed. One of the security holes plugged in iOS 10.1 has to do with a memory corruption issue in which malicious code could be installed on your iPhone simply by viewing a JPEG:
If that’s too small to read here’s what it says:
Available for: iPhone 5 and later, iPad 4th generation and later, iPod touch 6th generation and later
Impact: Viewing a maliciously crafted JPEG file may lead to arbitrary code execution
Description: A memory corruption issue was addressed through improved memory handling.
CVE-2016-4673: Marco Grassi (@marcograss) of KeenLab (@keen_lab), Tencent
You don’t even have to click on a malicious URL or download nefarious code, unless you update your iPhone immediately you could be affected simply by viewing a corrupted JPEG, and that’s some scary shit right there.
All you need to do in order to update your Apple iPhone to iOS 10.1 is open your phone, click Settings -> General -> Software Update and choose to download and update your phone. I’d suggest backing up your iPhone beforehand in iTunes because it’s always a good idea to backup your device before updating.
I did this update last night when I first came across this security vulnerability over on NYMag and it did seem to take longer than usual but that might’ve just been because I was sitting in bed and wanted to be playing with my new iPhone 7, so I was staring at the progress bar the entire time.
