I'm trying to improve LiveOverflow's current sudo fuzzing series, by adding driller to the project.
Since the Baron SameEdit vulnerability is triggered by using sudoedit, driller shall add 'edit' to the afl queue but sadly i get an error.
I created a Dockerfile so you can easily recreate my current state:

FROM aflplusplus/aflplusplus
ARG DEBIAN_FRONTEND=noninteractive
RUN useradd -ms /bin/bash user
RUN apt-get update && apt-get install -yq build-essential gcc-multilib debootstrap debian-archive-keyring libtool-bin bison python3 python3-pip virtualenv git python3-dev automake lsb-release xxd
RUN virtualenv -ppython3 /opt/venv
RUN /opt/venv/bin/pip install git+https://github.com/angr/archinfo
RUN /opt/venv/bin/pip install cle
RUN /opt/venv/bin/pip install git+https://github.com/angr/claripy
RUN /opt/venv/bin/pip install angr
RUN /opt/venv/bin/pip install git+https://github.com/angr/tracer
RUN /opt/venv/bin/pip install git+https://github.com/shellphish/driller
RUN cd / && git clone https://github.com/SpaceMoehre/sudofuzz
WORKDIR /sudofuzz
RUN make clean && ./configure --disable-shared && make && make install
RUN mkdir /tmp/in && mkdir /tmp/out && echo 'init' > /tmp/in/seed
CMD afl-fuzz -Q -i /tmp/in -o /tmp/out -M fuzzer-master ./src/sudo

For some reason i get errors when trying to install cle, angr via git+https, because of versioning...

build and run:

docker build - < Dockerfile
docker run -it <image id>

This will start the afl-fuzzer in qemu mode. in a second terminal i try to run my driller script:

source /opt/venv/bin/activate
python run_driller.py src/sudo /tmp/out/fuzzer-master

This results in the following error:

I tested a few things and turns out the libutil used by qemu and driller pointed to the same file and aflplusplus does not appear to be the problem, manually set aslr=False in the tracer.py and disabled aslr but the error persists.

Do you solver this problem？ I have met problem same to this.
