In this short tutorial we will go over how to reproduce the crash from CVE-2020-8597. This is a stack-based buffer overflow in the pppd binary.
We will use our own pppd binary compiled from source, using the latest version: 2.4.8.
To accomplish this goal, we will need two Virtual Machines connected by a virtual serial port. I typically use VirtualBox since it is open source, but the same sort of configuration should work on other hypervisors.
I spun up two VMs:
| use borsh::{BorshDeserialize, BorshSerialize}; | |
| use std::collections::HashMap; | |
| use std::convert::TryInto; | |
| use solana_program::{ | |
| account_info::{next_account_info, AccountInfo}, | |
| entrypoint, | |
| entrypoint::ProgramResult, | |
| msg, | |
| program_error::ProgramError, |
