Abstract
Differential coverage-guided feedback (CGF) fuzzing system and methods are provided to identify regressions in a software application. A computing device is configured to execute instructions that perform a fuzzing iteration. The fuzzing iteration includes operations that generate input data based on an initial corpus of samples; communicate the input data to a first application such that the first application performs operations utilizing the input data; collect first coverage information from the first application to identify first regressions; communicate the input data to a second application such that the second application performs operations utilizing the input data; and collect second coverage information from the first application to identify second regressions. The instructions additionally include: compare the first coverage information and the second coverage information; and perform another fuzzing iteration, wherein the computing device is configured to execute instructions that generate input data based on the compared first and second coverage information.
