The Guardian is reporting on an iOS bug ...
A flaw in the way Apple software handles images allows hackers to take over an iPhone, iPad, Apple Watch, Mac or Apple TV with a simple iMessage or email.
The vulnerability in Apple's picture-handling Image I/O API means that a malicious Tagged Image File Format (TIFF) file can force a so-called buffer overflow, which allows a hacker to break through Apple's security and run their own code on a device.
Lots of apps use this API such as Messages, MMS, Safari, Mail.
Should the image be viewed automatically or manually, the attacker could then gain full control of the device, steal passwords and other information, all potentially without the user knowing.
Apple has released iOS 9.3.3, OS X 10.11.6, tvOS 9.2.2 and watchOS 2.2.2 to fix the bug.
Finally...
There are 1bn iOS devices around the globe, all of which will be affected by this security hole unless updated.

You could also execute shellcode at kernel level in windows using TIFF.
