A new exploit has been discovered on the second generation model of iPod Touch that can help developers to create new jailbreak tools in future. The exploit discovered is different from the one that is being used in the SHAtter jailbreak that reportedly can help users to permanently jailbreak their iOS devices.
Explaining the new hack, the iPhone Wiki website explains,
“A heap overflow exists in the iPod touch 2G (both old and new) bootrom’s DFU Mode when sending a USB control message of request type 0xA1, request 0×1.
On newer devices, the same USB message triggers a double free() when the image upload is marked as finished, also rebooting the device (but that’s not exploitable because the double free() happens in a row). posixninja analyzed and explained this one.”
The exploit can be used to jailbreak both MC and non-MC versions of iPod Touch 2G devices – that’s models using the older as well as newer bootroms. We will see if jailbreakers make use of this newly discovered exploit in future jailbreak tools.
