iOS ipsw | Download iOS 4.3.4 For iPhone, iPad and iPod touchSome time ago it was expected that iOS 4.3.3 might be the last version of the iOS 4.x series from Apple before shifting to the iOS 5 which is a major upgrade over the current iOS 4.x versions. However, as we have seen the recent leak of the JailbreakMe 3.0 tool to allow untethered jailbreak of the iPad 2. Shortly after, we witnessed the official release of the tool by the @Comex. JailbreakMe 3.0 is in fact the simplest tool available to perform the jailbreak on the iDevices. This progress apparently forced Apple to release a minor update to the iOS namely iOS 4.3.4 that explicitly fixes the PDF based vulnerability that could allow to run arbitrary code on the compromised system. In fact, this is the vulnerability that has been exploited by the JailbreakMe 3.0 to do its untethered JB magic on the iPad 2.

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.

You can update to the latest iOS 4.3.4 directly from the iTunes or alternatively use the direct links provided below to download the IPSW file for your respective device to the computer and update the device via iTunes. Note that updating to the iOS 4.3.4 will block your ability to jailbreak your iPad 2 or other iDevice using the JailbreakMe 3.0. So, this is not a recommended update for anyone relying on the jailbreak of their iDevice. You can patch the PDF vulnerability by using the PDF Patcher 2 available directly from Cydia instead.
