What's worse than knowing that innocent JPEGs, PDFs, or font files can overshadow your iPhone, iPad, or iPod?
Yes, attackers can remotely compromise vulnerable Apple iOS devices, and all they have to do to do that is trick you into viewing a maliciously crafted JPEG image or a malicious PDF file via a web page or email, which could allow them to execute malicious code on your system.
This is a terrible flaw, but the good news is that Apple has released the latest version of its mobile operating system, iOS 10.1, to address this malicious code on iPhones and iPads, along with a number of bug fixes.
So users running older versions of iOS are advised to update their devices to iOS 10.1 as soon as possible.
In addition to the malicious code, iOS 10.1 also includes security updates to address 11 security vulnerabilities in the iPhone, iPad, and iPod Touch firmware.
To update your iOS device, follow the instructions: Settings → General → Software Update.
Apple has also released security updates for Mac computers, Apple Watches, and Apple TVs to make sure it protects all of its products.
Therefore, Mac users are advised to update their system to macOS Sierra (10.12.1), Apple Watches users to watchOS 3.1 software, and finally Apple TV users to update their televisions to the latest version tvOS 10.0.1.
