iPhone: Lockscreen security flaw found in iOS 6.1.3

Apple's iPhone has a new security flaw, just one day after its last major security issue was fixed.

Apple released iOS 6.1.3 on Tuesday to patch a security hole involving the phone’s lockscreen. Previous versions of the phone’s operating system allowed unauthorized users to make calls, view and modify contacts, look at photos and sync the phone with iTunes—even if the phone was locked.

A new vulnerability was found today in the patched software, though it doesn’t allow nearly as much access to a locked phone.

YouTube user “Barraquito” uploaded a video today showing the patched software being exploited by using a paper clip to eject the phone’s SIM card while using the voice-dialing function. This vulnerability only applies to phones with removable SIM cards, excluding phones like Verizon’s iPhone 4.

Apple hasn’t yet commented on the latest security hole.

A similar security flaw was found in locked Samsung Android phones on Wednesday as well.

Users with vulnerable iPhones are being advised to disable voice-dialing until a new patch is released.
