Abstract:In this paper, we present a smart fuzzing method for detecting six classes of heap‐based vulnerabilities in executable codes, that is, heap‐based buffer overflow, buffer underwrite, buffer over‐read, buffer under‐read, double‐free, and use‐after‐free vulnerabilities. In the proposed method, the executable code is instrumented to perform concolic (concrete + symbolic) execution and calculate the constraints on input data for executing a specific path. We also define a number of vulnerability constraints that de… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
