The FreeType library is used by Chrome to compute metrics and load hinted outlines from fonts. Overall, use of FreeType has been a huge win for Google. It does a complex job, and does it well, we rely on it extensively and contribute back to it. However, it is written in unsafe code and has its origins in a time when malicious inputs were less likely. Merely keeping up with the stream of issues found by fuzzing costs Google at least 0.25 full time software engineers. Worse, we observably don’t find everything or find things only after the code has shipped to users.
