Description-en: Library for coverage-guided fuzz testing
LibFuzzer is a library for in-process, coverage-guided, evolutionary fuzzing
of other libraries.
.
LibFuzzer is similar in concept to American Fuzzy Lop (AFL), but it performs
all of its fuzzing inside a single process. This in-process fuzzing can be
more restrictive and fragile, but is potentially much faster as there is no
overhead for process start-up.
.
The fuzzer is linked with the library under test, and feeds fuzzed inputs to
the library via a specific fuzzing entrypoint (aka 'target function'); the
fuzzer then tracks which areas of the code are reached, and generates mutations
on the corpus of input data in order to maximize the code coverage. The code
coverage information for libFuzzer is provided by LLVM's SanitizerCoverage
instrumentation.
