It is based on the concept of symbolic execution. Thus, the tool starts from a file considered valid by the software under test, and analyses the execution path to extract any constraints tied to branch instructions followed by this software. By resolving constraints one by one, Fuzzgrind will alter the valid file to explore possible new branches of the software under test, in order to discover new vulnerabilities.
