Following https://github.com/google/AFL/blob/master/docs/QuickStartGuide.txt
|
|
|
|
Compile this via (optionally using AFL_USE_ASAN=1, but that is horribly slow):
|
|
|
|
CC=afl-clang CXX=afl-clang++ cmake -B fuzzing \
|
|
-D CMAKE_RUNTIME_OUTPUT_DIRECTORY=$(pwd)/fuzzing \
|
|
-D SENTRY_BACKEND=none \
|
|
-D CMAKE_BUILD_TYPE=Release
|
|
|
|
cmake --build fuzzing --parallel --target sentry_fuzz_json
|
|
|
|
And then run:
|
|
|
|
afl-fuzz -i fuzzing-examples -o fuzzing-results -- fuzzing/sentry_fuzz_json @@
