Apple iOS 4.0.2 for iPhone and iPod touch and iOS 3.2.2 for iPad through iTunes has been released. This iOS update fixes a security hole that would allow malicious PDF files to compromise iOS.

The PDF security hole was used in the JailbreakMe website so that users could jailbreak their iPhones without running any special software; all they had to do was download a specially-created PDF file.

When Mobile Safari loads the PDF and reads the font section, it incorrectly executes the code inside the font section which takes advantage of an exploit to crack iOS.

Even with iOS 4.1 in the beta stages of its development, Apple has just released an emergency update: iOS 4.0.2. The purpose of the update appears to be solely focused on patching out the PDF exploit.
