WebFuzz Testing is a dynamic testing method for finding functional bugs and security issues in software. During a fuzz test, a program or a function under test gets executed with thousands of invalid, unexpected, or random inputs in order to crash the application, like a stress test for your application code. Feedback-based Fuzzing. WebAFL_LLVM_LTO_STARTID sets the starting location ID for the instrumentation. This defaults to 1. AFL_LLVM_MAP_ADDR sets the fixed map address to a different address than the default 0x10000. A value of 0 or empty sets the map address to be dynamic (the original AFL way, which is slower). AFL_LLVM_MAP_DYNAMIC sets the shared …
