The PlayStation 4 browser is arguably the most targeted attack surface for a console jailbreak. However, the hardening techniques enjoyed by current browsers coupled with the lack of debugging capability make it difficult to exploit bugs on the latest PS4 firmware.

This presentation details the exploitation strategy we adopted in order to exploit a 0-day vulnerability in WebKit. This is a Use-After-Free vulnerability which initially only offers limited primitives. However, thanks to a weakness identified in ASLR, it was possible to exploit this vulnerability leading to the first public jailbreak on version 7 of the PS4.
