This script contains some useful functions when it comes to Python scripting in gdb. I was bored to copy them again and again when doing reversing challenges so I decided to create a little wrapper containing all of them.
This repo is public because I feel like there are not that many ressources about Python scripting in gdb. This was written for my personnal usage and environnement when doing reverse engineering challenges so do not expect it to work flowlessly at any time.
Please note that this should NEVER be run as root as I create and delete a temporary file when getting the binary entry point. Even if the filename is randomized the risk is useless.
Of course this will always be a work in progress as I will add features and fix the code directly and only on the master branch because I'm lazy. Thus again do not expect it to work at any time, I'm just sharing this because I'm pretty sure it could help someone one day.
You can either copy the functions that interest you manually and import the gdb module to keep the verbose interface during execution, or import this module directly:
import gdbpython
import gdbpython as g
from gdbpython import *You must add this repository to your PYTHONPATH to import the module:
export PYTHONPATH=$PYTHONPATH:/path/to/gdb-pythonThe followings packages are required to enjoy every functions of the script:
readelf
gdb
I HIGHLY suggest to use it with gef. Not only because it is an insanely powerful tool but also because some commands as PIE breakpoints will not work in vanilla gdb. The following Python3 libraries are also required:
gdb
os
tempfile
random
string
Then you can use your script like this:
gdb -q -x script.py
Still in progress. See comments above functions until it's done.
