disconnect3d / 300.py

Created January 3, 2018 08:07 — forked from sroettger/300.py

One solution for the 34c3ctf's 300 heap challenge.

	#!/usr/bin/env python2
	# -- coding: utf-8 --

	# The 300 challenge was a heap challenge that allowed you to make allocations of size 0x300.
	# You could free allocations and read/write to them even after they got freed.
	# The tricky part about the challenge was that you don't control the size and can't for example use the usual fastbin techniques.

	# This exploit overwrites the check_action variable so that the libc doesn't abort on errors anymore.
	# Afterwards we can get a write-what-where primitive using unsafe unlink.
