GADGET DESIGNER Apple could be forced to update its iOS mobile operating system, again, following reports of an iOS 6.1 security vulnerability that allows unauthorised access to iPhone handsets.
A user video posted to Youtube demonstrates a technique in which a user is able to manipulate the "emergency call" feature of the iPhone to bypass the four-digit security code required to access the iOS home screen.
Designed to allow access to emergency lines, the emergency call button is the only feature accessible on the iPhone prior to entering the user's access code. The button displays a keypad that can only be used to dial emergency lines.
Users found that when the emergency call screen is accessed and cancelled a number of times while holding down the iPhone's power button, the iOS home screen could eventually be accessed without the need to enter the log-in code. The process has since been tested and confirmed a number of times.
Apple has yet to respond to a request for comment on the video.
Apple's iOS mobile operating system has seen similar bypass issues in the past. In 2008 users noted a simple procedure in which the emergency call feature could be manipulated to redirect to the home screen without the need for a security code.
The report comes in the wake of another bug in iOS 4.1 involving Microsoft Exchange. The flaw, which was not considered a security risk, caused the iPhone to conduct unnecessary communication with Exchange servers, draining battery life and causing excessive network traffic. µ
