Apple will repair the leak with iOS 10.1 update
The Monday published iOS 10.1 fixes a vulnerability that an attacker with a malicious jpeg file could use.
Apple announces the closing of the leak in the detailed description about iOS 10.1.
Attackers can leak exploit a custom jpeg image to send. Due to an error in the way images are loaded into memory is only the view of such a rogue image is enough to execute code.
It is not known what opportunities the abuses of the leak offered. Also, it is not known whether the leak is only in iOS 10, or also in older versions of iOS.
It is not the first time that a mobile operating system vulnerable for malicious image files. For instance, in Android, by 2015 the major Stagefright-leak discovered. That vulnerability gave attackers the chance for malicious code to hide in an image file.
Apple fixed it in July of this year, a similar flaw in iOS, when using images from the tiff file.
