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.
