Worked on enhancing fuzz testing for the GPAC test suite within the google/oss-fuzz repository, focusing on improving fuzz_parse coverage and security. Leveraged Shell scripting to automate build processes, including the delivery of dictionary and options files to the OSS-Fuzz output directory for seamless integration with fuzzing engines. Introduced a comprehensive ISOBMFF dictionary and tailored fuzzing options, which enabled broader, dictionary-driven test coverage. The initial fuzzing run led to the detection and resolution of a denial-of-service vulnerability, demonstrating effective bug detection and risk reduction. Emphasized build automation and fuzz testing to deliver more reliable and resilient fuzzing outputs.
