However, just one day after the iOS 6.1.3 release, another passcode security flaw has been discovered. It looks like that this vulnerability affects the iPhone 4 and iPhone 5, and involves the Voice Dial command as shown in the video above.

This security flaw giving a potential intruder access to both contacts and photos. The hack involves a complicated set of steps that includes initiating Voice Dial command and quickly ejecting the phone’s SIM card. iPhoneBlog.de reports that it has reproduced the issue on an iPhone 5 with Siri disabled

But don’t worry, this vulnerability can be fixed by disabling Voice Dial from the Passcode Lock menu.
