Throwaway Repository

Instructions

Follow the steps in the isosceles article to download and build libwebp and bad.webp. Copy bad.webp into this directory.

After that, apply libwebp.patch with git apply libwebp.patch.

Build simple_api_fuzzer (inside libwebp):

$ make -f makefile.unix clean
$ make -f makefile.unix
$ make -f makefile.unix src/mux/libwebpmux.a
$ cd tests/fuzzer
$ make -f makefile.unix

Note that this will build libwebp without any fuzzing instrumentation.

Build tracer with make tracer.

Run python3 ./capture_snapshot.py to create a memory snapshot just before fuzzing starts.

Run python3 ./triton_solve.py to launch the symbolic execution on the memory snapshot.
