Abstract

A method for identifying vulnerable system call pairs is disclosed. The method is based on a model for identifying Time-Of-Check-To-Time-Of-Use (TOCTTOU) problem (called STEM), which enumerates the potential file system call pairs (called exploitable TOCTTOU pairs) that form the check/use steps. The system function calls are classified into a plurality of predefined classes and pairs of the function calls are formed according to predefined criteria, where the function calls within a pair are associated with the same file invariant.
