Honggfuzz
Multi-threaded, feedback-driven fuzzer using software and hardware coverage counters to uncover memory corruption defects.
Technical Architecture & Overview
Honggfuzz is a multi-process, multi-threaded fuzzing engine. It supports software-based coverage (SanitizerCoverage) and hardware-based coverage (Intel PT/BTS), making it suitable for fuzzing large, complex, and binary-only targets.
Targeted Technical Use Cases
Fuzzing large software projects and binary-only targets using hardware-based coverage feedback.
Evaluation & Trade-offs
Core Strengths
- +Supports hardware-based coverage via Intel Processor Trace (PT) and Branch Trace Store (BTS).
- +Multi-process architecture isolates crashes, allowing fuzzing to continue after a target crash.
- +Used in OSS-Fuzz and Android security testing.
Trade-Offs & Limitations
- -Hardware coverage features require specific Intel CPU support.
- -More complex configuration than libFuzzer for simple in-process fuzzing.
Defensive Security Application
Finding memory corruption bugs in complex software through continuous hardware-assisted fuzzing.
