What is go-fuzz?

Go-fuzz is a specialized fuzzing tool that utilizes coverage guidance to effectively test Go packages, making it particularly adept at handling complex inputs, whether they are textual or binary. This type of testing is essential for fortifying systems that must manage data from potentially unsafe sources, such as those arising from network interactions. Recently, go-fuzz has rolled out preliminary support for fuzzing Go Modules, encouraging users to report any issues they experience along with comprehensive details. The tool creates random input data, which is frequently invalid, and if a function returns a value of 1, it prompts the fuzzer to prioritize that input for subsequent tests, though it should not be included in the corpus, even if it reveals new coverage; conversely, a return value of 0 indicates the opposite, while other return values are earmarked for future improvements. It is necessary for the fuzz function to be placed within a package recognized by go-fuzz, thus excluding the main package from testing but allowing for the fuzzing of internal packages. This organized methodology not only streamlines the testing process but also enhances the focus on discovering vulnerabilities within the code, ultimately leading to more robust software solutions. By continuously refining its support and encouraging community feedback, go-fuzz aims to evolve and adapt to the needs of developers.

What is Honggfuzz?

Honggfuzz is a sophisticated software fuzzer dedicated to improving security through its innovative fuzzing methodologies. Utilizing both evolutionary and feedback-driven approaches, it leverages software and hardware-based code coverage for optimal performance. The tool is adept at functioning within multi-process and multi-threaded frameworks, enabling users to fully utilize their CPU capabilities without the need for launching multiple instances of the fuzzer. Sharing and refining the file corpus across all fuzzing processes significantly boosts efficiency. When the persistent fuzzing mode is enabled, Honggfuzz showcases exceptional speed, capable of running a simple or empty LLVMFuzzerTestOneInput function at an astonishing rate of up to one million iterations per second on contemporary CPUs. It has a strong track record of uncovering security vulnerabilities, including the significant identification of the sole critical vulnerability in OpenSSL thus far. In contrast to other fuzzing solutions, Honggfuzz can recognize and report on hijacked or ignored signals resulting from crashes, enhancing its utility in pinpointing obscure issues within fuzzed applications. With its comprehensive features and capabilities, Honggfuzz stands as an invaluable resource for security researchers striving to reveal hidden weaknesses in software architectures. This makes it not only a powerful tool for testing but also a crucial component in the ongoing battle against software vulnerabilities.
