On Friday, Apple released iOS 4.3.4, the latest incarnation of its iOS operating system for its iPhone, iPod touch and iPad devices. The updates, which somewhat function as a response to the German government’s regarding PDF-related security vulnerabilities in MobileSafari fix the same three vulnerabilities, the patch arriving in two versions, thanks to the different flavors of the iPhone 4. iOS 4.3.4 applies to the iPad and iPad 2, the third- and fourth-generation iPod touch, the iPhone 3GS, and the iPhone 4 (GSM model); users of the CDMA model of the iPhone 4 instead get iOS 4.2.9.

Per Macworld, the issues addressed in the updates include the aforementioned PDF problem within Apple’s CoreGraphics framework, which exploits FreeType’s TrueType and Type 1 fonts to execute malicious code, and a conversion problem within the IOMobileFrameBuffer framework, which could allow code to inadvertently gain system privileges by posing as the user.

These updates can be snagged by plugging in your respective iOS device and checking for updates in iTunes.

If you’ve tried the updates and noticed any differences, please let us know in the comments.

  1. Here is a similar story

    The jailbreak comes either in the form of a custom 4.3.4 bundle to be
    used with PwnageTool or simply by using the newly updated redsn0w tool.
    It is a tethered jailbreak, meaning if your device is restarted, the
    jailbreak must be reinstalled. RedmondPie’s jailbreak does not work on
    iPad 2.
