WebS2E is a platform for writing tools that analyze the properties and behavior of software systems. S2E comes as a modular library that gives virtual machines symbolic execution and program analysis capabilities. S2E runs unmodified x86, x86-64, or ARM software stacks, including programs, libraries, the kernel, and drivers. Symbolically executing all feasible program paths does not scale to large programs. The number of feasible paths in a program grows exponentially with an increase in program size and can even be infinite in the case of programs with unbounded loop iterations. Solutions to the path explosion problem generally use either heuristics for path-finding to increase code coverage, reduce execution time by parallelizing independent paths, or by merging similar paths. One example of … christian kuhn montumWeba new symbolic execution tool, KLEE, which we de-signed for robust, deep checking of a broad range of ap-plications, leveraging several years of lessons from our previous tool, EXE [16].
