Web-Based iOS 4 Jailbreaking Tool Exposes Security Vulnerability

http://erictric.com

A few days ago, a new web-based iOS 4 jailbreaking tool properly called “JailbreakMe” was released. The tool quickly became popular and was praised for its innovation and simplicity. However, JailbreakMe is making headlines once again for a totally different reason. Turns out that the JailbreakMe utilizes a security vulnerability in iOS to be able to do its duty. However, concerns have been raised that malicious individuals could exploit the same security vulnerability to deliver malware attacks on any of the iOS-based devices such as iPhones, iPod Touches, and iPads. The security hole is found on the iOS PDF viewer. Specially-crafted fonts are embedded into a PDF document. Processing the embedded font causes a stack overflow, which will allow the program to easily bypass the iOS security. Thereby allowing hackers to take full control of the device. The rest, as they say, is history. JailbreakMe itself is currently a benign tool. However, we can’t say the same about the many hackers lurking through the dark alleys of the Internet searching for unsuspecting victims. The JailbreakMe tool could potentially be reverse-engineered to pull off their malevolent plans.

iPhone 4 jailbreak unlocks FaceTime via 3G and a malicious exploit

http://www.gottabemobile.com

News of a successful and easy-to-apply jailbreak for the iPhone 4 and other iOS devices lit up the Internet, followed quickly by news of patches for broken functionality, FaceTime calling over 3G, and a malicious exploit with an opponent named Warner. Kicking things off was the launch of JailbreakMe.com (via Engadget), a website that jailbreaks (unlocks root access) to your iDevice up to the iPhone 4 running the latest version of iOS. I don’t know exactly how it works, but it all happens through the Safari web browser, which means exploiting a security flaw to initiate the process. You do risk bricking your iDevice and/or voiding your warranty with a jailbreak, not to mention leaving your device vulnerable if you don’t change the root password. There’s no longer a law against jailbreaking your iPhone, but that doesn’t eliminate all the risks involved. If all that raises a red flag for you, good. I really don’t advocate any hacking that’s beyond your ability to understand, so just make sure you’re cool with everything good and bad before taking the plunge. On the good side of things, jailbreaking your iPhone 4 enables FaceTime calls over 3G using an app called My3G.

JailbreakMe Exploits Serious iPhone Security Flaw

http://www.pcworld.com

JailbreakMe makes the process of jailbreaking the Apple iPhone much simpler and less intimidating. Just visit a Web site on the iPhone, and voila! Jailbroken iPhone. Think about that for a minute, though. The simple act of visiting a Web site is able to fundamentally alter the core functionality of iOS. Since the dawn of the iPhone, hackers have developed various tools and processes to enable users to circumvent the controls and restrictions put in place by Apple. In the wake of the United States Copyright Office ruling that jailbreaking the iPhone is technically legal--at least from a copyright and DMCA (Digital Millennium Copyright Act) perspective--having a tool that can accomplish it simply by visiting a Web site is awesome for less technically savvy iPhone owners. However, if JailbreakMe is capable of unlocking the iPhone operating system by taking advantage of a flaw in the way the iPhone renders Adobe PDF files, then other applications can also exploit that same flaw for less-benevolent goals. What JailbreakMe illustrates is that the iPhone has a serious security issue that Apple needs to address.For companies that allow the iPhone to connect with network resources
