getlibc

A shell script to pull the libc and ld-linux loader file from a Docker image. Useful for pwn.

It detects the use of a redpwn jail container and grabs the correct libc (the one that applies to the challenge file in /srv).

Install

git clone https://github.com/OBarronCS/getlibc.git ~/getlibc

bash

echo 'export PATH="$HOME/getlibc/bin:$PATH"' >> ~/.bashrc

zsh

echo 'export PATH="$HOME/getlibc/bin:$PATH"' >> ~/.zshrc

Usage

Running getlibc will grab the libc and the dynamic loader from the container and place them in the current directory. If the file names already exist, it will not overwrite them.

With no arguments, it looks for a Dockerfile in the current directory. Otherwise, you can specify the path or the Docker image name.

getlibc [-f Dockerfile_path] [--image Image_name]
