A Framework for Fuzz Target Generation and Evaluation

The project under analysis is a framework designed to generate fuzz targets for C/C++ projects using Large Language Models (LLMs) and evaluate them on the OSS-Fuzz platform. The goal is to leverage AI to create more effective fuzzing targets and improve upon traditional bug hunting methods. The framework also assesses the generated fuzz targets using metrics like compilability, runtime crashes, and coverage metrics. Notably, the project has reported two vulnerabilities and has shown significant coverage improvements in several open-source projects.

Apparent Problems and TODOs:

• The lack of public reports containing vulnerabilities may limit external contributions and validation.
• The need for a detailed usage guide suggests that the framework might not be straightforward to use.
• The project's call for research or open-source community collaborations indicates it is still in a phase where external input and development are required.
