摘要
A method of branch exploration in fuzz testing of software binaries includes receiving a set of inputs of a binary program under analysis (BPUA) discovered during testing by a grey box fuzzer. The method includes re-executing the set of inputs. The method includes re-executing a concrete execution of the set of inputs in the BPUA and formation of a constraints tree in which path constraints along paths of the BPUA and conditions at branch points are recorded and marked as explored or unexplored. The method includes selecting a particular number of the unexplored branches of the BPUA. The method includes solving the particular number of unexplored branches with a constraint solver to generate a new set of the particular number of inputs. The method includes communicating the new set of the particular number of inputs to the grey box fuzzer for exploration of different branches of the BPUA.
