Via iTunes, Apple has released iOS 4.3.4, a minor update of its firmware for the iPhone, iPad and iPod touch. The update appears to concentrate primarily on security issues, namely the possibility of exploits using malicious PDF files. Vulnerabilities were present in FreeType's handling of TrueType and Type 1 fonts. A hole in IOMobileFrameBuffer, meanwhile, theoretically allowed an attacker to get system privileges.
