Breizh CTF 2024 - Write-up MTE - Pwn

og:description

Here is the write-up of MTE challenge which I created for the Breizh CTF 2024. This is a Pwn challenge classified as difficult/very difficult. Description Do you know MTE? It's a new feature on the latest ARM CPUs, no more exploitation in the heap, what happiness! I've implemented it on top of glibc in a little binary emulated via qemu, so you can't pwn it, but ... Reverse For this challenge, we have an aarch64 binary, and from the description, we know it implicates implementation of MTE technology over glibc.
