libFuzzer in Chromium

go/libfuzzer-chromium (Googler only)

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

Requirements: libFuzzer in Chromium is supported with Linux and Mac only.

Integration Status

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

Documentation

  • Getting Started Guide walks you through all the steps necessary to create your fuzzer and submit it to ClusterFuzz.
  • Efficient Fuzzer Guide explains how to measure fuzzer effectiveness and ways to improve it.
  • Guide to libprotobuf-mutator walks through the steps necessary to create a fuzzer that libFuzzer gives mutated protobufs to as input (for developers already familiar with libFuzzer).
  • ClusterFuzz Integration describes integration between ClusterFuzz and libFuzzer.
  • Reproducing contains information on how to reproduce bugs reported by ClusterFuzz.
  • Reference contains detailed references for different integration parts.

Trophies

  • ClusterFuzz Bugs - issues found and automatically filed by ClusterFuzz.
  • Manual Bugs - issues that were filed manually after running fuzzers.
  • Pdfium Bugs - bugs found in pdfium by manual fuzzing.
  • OSS Trophies - bugs found with libFuzzer in open-source projects.
