Fuzzers for font parsers, such as freetype need extensive seed corpora to be efficient.
We are using seed inputs from the following sources:
- Chromium sourcess
- Skia
- Harfbuzz
- https://github.com/google/fonts
- Fonts from Ubuntu (install all font-related packages, then loot
/usr/share/fonts) - https://github.com/adobe-fonts
- https://github.com/Pomax/CFF-glyphlet-fonts
