In this paper we develop a security verification framework for open source software with a multi-language support. We base our approach on the GCC compiler which is considered as the defacto open source compiler for several languages including C, C++, JAVA, ADA, FORTRAN,etc. To achieve our goal we use a conventional push down system model-checker for reachability properties, and turn it into a fully-fledged...
In this paper, we present a novel type and effect analysis for detecting memory errors in C source code. We extend the standard C type system with effect, region, and host annotations that hold valuable security information. We define static security checks to detect errors using the annotations. The checks are compliant with the ANSI-C standard, while adding more security restrictions to prevent...
In this paper, we present a novel type and effect analysis for detecting type cast errors and memory errors in C source code. Our approach involves a type system with effect, region, and cast history annotations that hold valuable information for ensuring memory safety. The cast history is a precise type decoration we define to address C type casting issues. Our flow-sensitive annotations are allowed...
