PROFILE
Fabio Gritti
Worked on the libsdl-org/libtiff repository to enhance the OSS-Fuzz TIFF image fuzzer by implementing support for non-tiled image handling. This involved adding logic in C to check row and strip sizes, mitigating out-of-memory risks during fuzzing and improving the reliability of memory management. The approach included allocating and reading scanlines for non-tiled images, which expanded fuzzing coverage and strengthened detection of edge-case vulnerabilities. Focus remained on input handling and robustness rather than bug fixes, with changes aimed at improving security testing. Demonstrated skills in C programming, fuzzing, image processing, and integration with OSS-Fuzz for regression testing.

Dec 1, 2024December 2024 monthly summary for libsdl-org/libtiff. Key feature delivered: OSS-Fuzz TIFF Image Fuzzer Non-Tiled Image Handling. This work adds non-tiled image handling to the TIFF fuzzer, including row size and strip size checks to mitigate out-of-memory risks and allocating/reading scanlines for non-tiled images to improve fuzzing coverage and robustness. Major bugs fixed: None reported this month; changes focus on fuzzing robustness and input handling to prevent OOM and edge-case failures. Overall impact: strengthens security testing and reliability of OSS-Fuzz integration for non-tiled TIFFs, expanding coverage and reducing crash surface. Technologies/skills demonstrated: C/C++, fuzzing and OSS-Fuzz integration, memory management, TIFF internals, code instrumentation, and regression testing.
