iOS 4.3.4 Prevents Hacking and Jailbreaking

Mightee writes "Apple has released a software update to iOS, version 4.3.4, for the iPhone 4, 3GS, iPad 2, 1, and iPod Touch. The main objective of this version is to prevent the hacking in Apple iOS devices which occurs through malicious PDF files. Another objective is to prevent the jailbreaking which occurs as a consequence of the previous effect. In previous versions, the iOS device is easily vulnerable to attacks. It happens because of mishandling of fonts embedded in the PDF file. Sometimes a downloaded PDF may be malicious, and there is a possibility that the file could inject malware into the iOS device, which gives a chance for the hackers to access the hardware of the iOS device."
