libFuzzer in Chrome

go/libfuzzer-chrome

This directory contains integration between libFuzzer and Chrome. libFuzzer is an in-process coverage-driven evolutionary fuzzer. It helps engineers to uncover potential security & stability problems earlier.

Requirements: libFuzzer in Chrome is supported with GN on Linux only. Check Reference for experimental platform availability.

Integration Status

Fuzzer tests are well-integrated with Chrome build system & distributed ClusterFuzz fuzzing system. Cover bug: crbug.com/539572.
