| Super Smash Brothers for Wii U is vulnerable to contenthax attacks via a crafted moveset file that causes a buffer overflow from the moveset's stack buffer into the stored write index of said stack allowing for a contiguous relative read/write which can be used for an address leak to translate it into an arbitrary read/write. A proof of concept and write up can be found [https://github.com/jam1garner/ROBChain here].
