OSmart: Whitebox Program Option Fuzzing

Program options are ubiquitous and serve as a fundamental mechanism for configuring and customizing software behaviors. Given their widespread use, testing program options becomes essential to ensure that the software behaves as expected across various configurations. Existing option-aware fuzzers either mutate options as if they were standard program inputs or employ NLP techniques to deduce relationships among options from the documentation. However, there has not been a whitebox approach that generates option combinations by capturing the inherent execution logic of the program.
