Honggfuzz – Simple Command Line Software Fuzzing Tool

Outsmart Malicious Hackers


Honggfuzz is a general-purpose fuzzing tool. Given a starting corpus of test files, Hongfuzz supplies and modifies input to a test program and utilize the ptrace() API/POSIX signal interface to detect and log crashes.

Basically it’s a simple, easy to use via command-line interface, providing nice analysis of software crashes in a simple form of file names.

It has been used to find a few (possibly exploitable) bugs in some major software packages including freetype2, librsvg and libtiff.

Features

  • Easy setup: No complicated configuration files or setup necessary — Hongfuzz can be run directly from the command line.
  • Fast: Multiple Hongfuzz instances can be run simultaneously for more efficient fuzzing.
  • Powerful analysis capabilities: Hongfuzz will use the most powerful process state analysis (e.g. ptrace) interface under a given OS.
