Apple has just released iOS 4.0.2 for iPhone and iPod touch and iOS 3.2.2 for iPad through iTunes. This update plugs 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.
