In this article, we will show you how we found vulnerabilities in a large open-source project with libFuzzer.

We are talking about suricata, an Intrusion Detection System and Intrusion Prevention System (IDS/IPS). Although the project already uses fuzzing with AFL extensively, we found 14 more bugs in the program code with libFuzzer, 12 of them being critical vulnerabilities (CVEs).

libFuzzer is a powerful tool, but it has a certain complexity. If you are looking for a more user-friendly way, you can read more about CI Fuzz. Download our Whitepaper to learn more.
