"No iOS Zone" denial-of-service vulnerability could lead to your iPhone or iPad constantly crashing.
The researchers say that they first informed Apple of the problem in early October 2014, and that iOS 8.3 appears to resolve some of the issues they uncovered.
Chances are that this won’t be the last time that a serious denial of service flaw is found in iOS. Just last month, Apple released iOS 8.2 which fixed a flaw that allowed hackers to restart iPhones by sending them a maliciously-crafted Flash SMS.
More details of the “No iOS Zone” flaw can be found in the slide deck of the presentation given at the RSA conference.
