After the release of iOS 6.1.3, yesterday which fixed a lockscreen flaw that allowed access to contacts, a new security opening has been found in the iPhone 3GS, 4, 4s, 5 and iPad 2,3,4. The update also blocks jailbreaking by EvasiOn and fixed other problems.
For data thieves with time and the iPhone in their hands they can get past the security code by using voice control to dial a number. Ejecting the SIM card during the dialing, will end the call and give open access to the address book and photos on the iPhone. The way to stop anyone from doing it is to shut off voice dialing.
Meanwhile iPhone jailbreakers are disappointed because EvasiOn jailbreaking will not work on iPhones and iPads running iOS 6.1.3.
Other problems fixed in the update 6.1.3 fixed vulnerabilities in the Kernel, Lockdown, USB and WebKit browser. In fact, Apple credited the jailbreak development team evad3rs discovered four of six vulnerabilities.
Apple noted that the automatic update process may take up to a week depending on the day that iTunes or the device checks for updates. You may manually obtain the update via the Check for Updates button within iTunes, or the Software Update on your device.
It has been taking two to four weeks for Apple to fix reported security flaws, if you are worried about the latest voice dialing, you can prevent it by shutting off voice dialing.
