Alt-pwninit

Auto getting linker, unstripping and getting the source codes of an Ubuntu or Debian GLibc.

Setup

Python dependencies are declared in pyproject.toml and managed with uv. Run make setup to install the system tools (patchelf, elfutils), ensure uv is installed, and create the project .venv (uv sync).

Usage

uv run uses the project's .venv:

uv run pwninit.py -b ./chall -l ./libc.so.6
# convenience shortcut:
make run ARGS="-b ./chall -l ./libc.so.6"

Run from anywhere

make install symlinks the pwninit wrapper into ~/.local/bin, so you can run it from any challenge directory (output files land in the current directory):

make install
pwninit -b ./chall -l ./libc.so.6

Libc.py can be used standalone too (-ld linker, -u unstrip, -src source):

uv run Libc.py ./libc.so.6 -ld -u

Testing

make test runs a Docker-based test matrix: it pulls real libc binaries out of Ubuntu/Debian images and checks that Libc.py can fetch the linker, unstrip the libc, and recover symbols. Requires Docker.

make test                              # default Ubuntu + Debian matrix
make test ARGS="ubuntu:22.04 debian:12"  # specific images only
