Exploit for the TurboFan challenge from Google CTF 2018

Just In Time is a an exploitation challenge written by Stephen 'tsuro' Röttger for Google CTF 2018.

I wrote an introduction to TurboFan article on doare-e.github.io that explains the bug and its exploitation.

When working on v8, I use a customized engine for which I added some features.
One of those is a on my other repo.

You may also want to have a look at a few experiments.

O

For just-in-time, you are provided with a modified v8 engine.

It contains a TurboFan reduction (understand : optimization pass).

This reduction tries to (incorrectly) optimize duplicate additions such as x + 1 + 2.

This repository contains a full exploit for this bug. It also uses WebAssembly to get RWX memory.
