Fuzzing libjpeg(-turbo)

Requirements

• honggfuzz
• clang-5.0, or newer
• libjpeg9, or libjpeg-turbo

Preparation

1. Compile honggfuzz

2. Unpack/Clone libjpeg(-turbo)

3. Configure+Compile libjpeg(-turbo)

CC=<your_hfuzz_dir>/hfuzz_cc/hfuzz-clang CXX=<your_hfuzz_dir>/hfuzz_cc/hfuzz-clang++ CFLAGS="-fsanitize=address" ./configure
make -j$(nproc)

4. Compile fuzzing targets

$ <your_hfuzz_dir>/hfuzz_cc/hfuzz-clang -I ./jpeg-9c/ <your_hfuzz_dir>/examples/libjpeg/persistent-jpeg.c -o persistent.jpeg9.address jpeg-9c/.libs/libjpeg.a  -fsanitize=address

or

$ <your_hfuzz_dir>/hfuzz_cc/hfuzz-clang -I ./libjpeg-turbo-2.0.3/ -I ./libjpeg-turbo-2.0.3/out/ <your_hfuzz_dir>/examples/libjpeg/persistent-jpeg.c -o persistent.jpeg-turbo.address libjpeg-turbo-2.0.3/out/libjpeg.a -fsanitize=address

Fuzzing

$ honggfuzz -i initial_corpus --rlimit_rss 2048 -- ./persistent.jpeg9.address 

or

$ honggfuzz -i initial_corpus --rlimit_rss 2048 -- ./persistent.jpeg-turbo.address
