UAF Fuzzing Benchmark

UAF Fuzzing Benchmark

We create a fuzzing benchmark of Use-After-Free (UAF) and Double-Free (DF) bugs for our evaluations. It includes recent bugs found by existing (directed) greybox fuzzers of real-world programs. We provide scripts, Valgrind's stack traces as targets and initial seeds of each subject. Please follow the instructions to install fuzzers like AFL(-QEMU), AFLGo and UAFuzz.

# Environment variables
export AFL=/path/to/afl-2.52b
export AFLGO=/path/to/aflgo
export IDA_PATH=/path/to/ida-6.9/idaq
export GRAPH_EASY_PATH=/path/to/graph-easy
export UAFUZZ_PATH=/path/to/uafuzz

# Avoid hang when fuzzing
export MALLOC_CHECK_=0

# Checkout the benchmark
git clone https://github.com/strongcourage/uafbench.git
cd uafbench; export UAFBENCH_PATH=`pwd`
