A serious security vulnerability has been found in iOS 6.1 that allows an attacker to bypass the passcode lock, and gain access to the Phone app, contacts, photos, and voicemail. As you can see in the video above, a series of button presses after attempting an emergency call can bypass the passcode lock. A similar vulnerability existed in previous versions of iOS, and it looks like it is back. iOS 6.0.1, 6.0.2, and 6.1 are all vulnerable to the attack.
Apple just rolled out iOS 6.1.1 to fix a serious cellular issue with the iPhone 4S. It looks like they will need to pop out another update soon to fix this vulnerability.
Apple's track record of late has been tarnished by a serious of software issues. The Maps debacle, iTunes Match bugs, iCloud bugs, and now iOS issues. What's happening over there? We use to know Apple as the company who made products that "just work" but they have had a string of issues lately.
