Alongside today's update to iOS 6.1.3, Apple also updated the Apple TV to version 5.2.1. The 5.2.1 software contains a number of bug fixes and has also brought a redesigned Hulu app to the device. The security fixes, which can all be credited to the evad3rs, prevent users from executing unsigned code, determining the address of structures in the kernel, and executing arbitrary code in the kernel. As for Hulu, the app has been entirely redesigned with improved discovery tools and some simple UI enhancements.
