Fuzzinator Release Notes

18.3.1

Summary of changes:

  • Fixed the way package metadata is accessed to ensure wheel compatibility.

18.3

Summary of changes:

  • New features in the framework:
    • Support for issue (re-)validation with a new job type (validate).
    • Support for user-defined event listeners.
  • Numerous new building blocks in the framework:
    • fuzzinator.EmailListener: support for sending emails about events, e.g., new issues.
    • fuzzinator.tracker.MonorailReport: support for the Monorail issue tracking system.
    • fuzzinator.call.LldbBacktraceDecorator: support for backtrace info via LLDB.
    • fuzzinator.fuzzer.ByteFlipDecorator: support for adding extra random byte flips to fuzzer results.
    • fuzzinator.fuzzer.FileWriterDecorator: support for writing fuzzer results to files.
    • fuzzinator.call.FileReaderDecorator: support for extracting fuzzer results from files.
  • Building blocks with extended or changed functionality:
    • fuzzinator.call.SubprocessCall and .StdinSubprocessCall can accept 0 exit code as an issue.
    • fuzzinator.call.StreamRegexFilter has been renamed to .RegexFilter to enable arbitrary filtering of issues, and can match multiple patterns.
    • fuzzinator.call.StreamMonitoredSubprocessCall regex patterns are multiline.
    • fuzzinator.fuzzer.AFLRunner supports AFL's master and slave concepts.
    • fuzzinator.fuzzer.ListDirectory works with a glob pattern instead of a simple directory name to collect test cases.
    • fuzzinator.fuzzer.SubprocessRunner and .ListDirectory can work both as file content generators and as file path generators.
    • fuzzinator.update.TimestampUpdateCondition supports time intervals longer than 24 hours.
    • All Popen-based subprocess-executing building blocks (fuzzinator.call.StdinSubprocessCall, .StreamMonitoredSubprocessCall, .SubprocessCall, .SubprocessPropertyDecorator, .TestRunnerSubprocessCall, fuzzinator.fuzzer.SubprocessRunner, and fuzzinator.update.SubprocessUpdate) have timeout support and avoid shell invocation.
    • fuzzinator.reduce.Picire has been updated to use Picire 18.1.
    • fuzzinator.reduce.Picireny has been updated to use Picireny 18.2.
    • All reporters (fuzzinator.tracker.MonorailReport, .BugzillaReport, .GithubReport) have been changed to use format string syntax ({key}) instead of template syntax ($key) in their report templates, and all handle missing keys gracefully.
  • TUI improvements:
    • Support for simpler custom color schemes.
    • More convenient bug report editor.
    • Support for both text and binary copying of test cases to the clipboard.
    • Support for declaring bug duplicates manually.
    • New and improved dialogs (about dialog, closing of dialogs).
    • Improved event handling (responsivity, updated issues, invalid issues).
  • General usability improvements:
    • More flexible configuration format enabling config sections to be split across multiple files, and keys to have no value.
    • Support for command line arguments specified in list files to help with config file fragments.
    • Useful command line argument aliases and new arguments (appearance, verbosity, Python interpreter limits, fuzz session length).
  • Under-the-hood improvements:
    • Improved logging.
    • Added testing infrastructure: unit testing of SUT calls, fuzzers, and SUT updaters via tox; continuous testing via Travis and AppVeyor CI services.
    • Added documentation: out-of-sources tutorial and auto-generated API docs via Sphinx; online documentation hosting on Read-the-Docs.
    • Various bug fixes and refactorings (in core components, in building blocks, and in user interfaces).

16.10

First public release of the Fuzzinator Random Testing Framework.

Summary of main features:

  • Core scheduler/controller of fuzzing-related jobs (update, fuzz, reduce).
  • MongoDB-based issue repository.
  • Extensible framework with predefined building blocks for invoking SUTs, detecting issues, and determining uniqueness; for generating test cases and transporting them to SUTs; for minimizing issue-triggering tests; and for keeping SUTs under development up-to-date.
  • Configurability via INI files.
  • CLI and Urwid-based TUI.
