All of us know that in file format fuzzing, we fuzz different aspects of a file such as flags, file format constraints, structures etc. by generating multiple malformed samples, opening them and waiting for the program crash. We then process the generated debug information to find out if we found something interesting in the crash. Surprisingly, there is a dearth of file format fuzzers. However, we now have OpenXMolar for the Microsoft Windows operating system. Read more about OpenXMolar: A OpenXML File Format Fuzzing Framework!
Fuzzing or fuzz testing is a system testing strategy that includes giving invalid, surprising, or irregular information as contributions to a system. The system is then checked for special cases, for example, crashes, or coming up short implicit code declarations or for discovering potential memory spills. Normally, fuzzers are utilized to test programs that take organized sources of information.
