Fuzzing Font Parsing

Fuzzing Font Parsing
Posted Oct 23, 2017
Authored by James Fell

This article presents a cross-platform test harness written in Python that assists the user in searching for vulnerabilities in web browsers, specifically by fuzzing their font parsing functionality. The tool automates the delivery of test cases (font files in this context) into a web browser. The creation of a corpus of mutated TTF font files suitable for use in fuzzing is also covered.
