Apple has just released iOS 4.3.4 to block the PDF security hole we heard of recently, which is also the door through which web jailbreak service Jailbreakme.com functions. Here’s the official description, courtesy of Apple:
Available for: iOS 3.0 through 4.3.3 for iPhone 3GS and iPhone 4 (GSM model), iOS 3.1 through 4.3.3 for iPod touch (3rd generation) and later, iOS 3.2 through 4.3.3 for iPad
Impact: Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution
Description: A buffer overflow exists in FreeType’s handling of TrueType fonts. Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution.
Available through the usual sources, but don’t upgrade if you’re jailbroken and want to stay that way.
