They have been numerous issues in need of resolution with iOS, some of which are outlined here.

Cloud Kit

It was feasible for a malicious application to acquire “the iCloud user record of a previously signed in user”. Improved state handling has resolved this.

Bluetooth

Apple discovered an issue whereby a malicious app could enter a Bluetooth paired Mac’s - or iOS device - notification center through its notification center service. It was settled through removing access to this service.

Improved cooking handling has fixed two issues that meant there was a chance of cookies being “leaked” during content security policy report requests.
