Fuzz-FFmpeg

In this example, we use Ubuntu 16.04 as our host OS and multiple supporting packages to properly support the FFmpeg install. We also added the afl-utils repo to the Docker image to support larger core nodes. Here is the Docker file that we used built to support this

Build & Deploy

  1. Pull the repo: https://github.com/killswitch-GUI/Fuzz-FFmpeg.git
  2. Building the Docker image can take some time honestly, it requires an install of many dependencies and compiles of the FFmpeg project. This can be easily done like so: docker-compose up -d --build
  3. Drop into Docker image interactively using the following command: docker exec -ti <DOCKER NAME HERE> bash. This due to the image being set up in daemon mode with an entry point that will not exit upon completion.
  4. Starting your workload is easy with afl-multicore, this automates the process of starting multiple instances with nohup: python3 /afl-utils/afl-multicore -c ffmpeg_afl_scripts/afl_mc_ffmpeg.json start 12
  5. There are many ways to check the status of your workload, it can be done with afl-stats or even grep:
cd /ffmpeg_output#
cat */fuzzer_stats | grep unique_crashes | uniq
cat */fuzzer_stats | grep unique_hangs| uniq
You can’t perform that action at this time.
