linux-container

Simple Ubuntu containers for debugging pwn problems.

Features

This repository provides a reproducible environment for binary exploitation (pwn) debugging. It uses Docker to set up the environment and a wrapper script for easier usage. Commonly used tools and libraries are included.

Installed packages and tools:

• System & Utilities: xz-utils, tmux, nano, vim, tree, curl, git, zsh

• Debugging: gdb, binutils-multiarch, glibc-source

• Programming: python3, pip, ruby-dev, rubygems

• Exploitation Tools:

  • pwntools (Python)
  • one_gadget (Ruby)
  • pwndbg (GDB plugin)

Additionally:

• Pre-configured glibc-2.xx directories for gdb debugging
• Shell & editor configs included (.zshrc, .tmux.conf, .vimrc)
• Default user (non-root) is automatically created and used

Usage

./vm [build|run|upload|connect]

• ./vm build – Build the container image
• ./vm run – Start the container
• ./vm upload [folder or file path] – Upload files or directories from host into the container
• ./vm connect – Attach to a running container

Notes

• Although this container tries to replicate the same debugging environment across systems, there may be differences in gdb behavior.

  • To find the exact offset:

    • Use the ELF and Dockerfile provided in the challenge, or
    • Use gdbserver to eliminate differences.
    • Attach gdb to the provided docker image directly.

• On Ubuntu 18.04, some packages had to be removed due to compatibility issues.
