Apple Patches iPhone PDF Security Flaw with iOS 4.3.4 Update

| News

Apple released iOS 4.3.4 and iOS 4.2.9 on Friday for the iPhone, iPad and iPod touch. The updates patch a PDF rendering security flaw that’s currently used to install the JailbreakMe jailbreak hack through Mobile Safari.

iOS 4.3.4 is available for the iPod touch, iPad, iPad 2 and GSM iPhone 3GS and iPhone 4. GSM is the cell network technology used by many mobile phone providers around the world in including AT&T in the U.S. CDMA is used by Verizon and isn’t compatible with GSM networks, requiring Apple to release a special iPhone 4 model just for their network.

The security flaw could potentially be used to install software without user authorization, although the only in-the-wild use of the threat is the JailbreakMe hack. JailbreakMe lets users jailbreak their iOS devices without requiring a connection to a computer. Jailbreaking is a process that hacks the device so third-party apps that aren’t available through Apple’s App Store can be installed and run.

The iOS 4.3.4 update and iOS 4.2.9 update are available as free downloads. Users can install the updates by connecting their device to iTunes.

Has anyone discovered any bug fixes in the 4.3.4 that are worthwhile ?

Supposedly the new “update” has already been hacked. Why oh why can’t they put in a 128 bit encryption to stop this? It would likely take years to break the cypher. It’s one thing to hack an OS and the FTC say they’re ok with it, but start hacking encryption cyphers and you’re gonna get into trouble with the big guys, including the FBI.
