The Fuzzing Project

This is already a few days old but I haven't announced it here yet. I recently started a little project to improve the state of security in free software apps and libraries:

The Fuzzing Project

This was preceded by a couple of discussions on the mailing list oss-security and findings that basic Unix/Linux tools like strings or less could pose a security risk. Also the availability of powerful tools like Address Sanitizer and american fuzzy lop makes fuzzing easier than ever before.

Fuzzing is a simple and powerful strategy to find bugs in software. It works by feeding a software with a large number of malformed input files usually by taking a small, valid file as a starting point. The sad state of things is that for a large number of software project you can find memory violation bugs within seconds with common fuzzing tools. The goal of the Fuzzing Project is to change that. At its core is currently a list of free software projects and their state of fuzzing robustness. What should follow are easy tutorials to start fuzzing, a collection of small input file samples and probably more ways to get involved (I think about moving the page's source code to github to allow pull requests). My own fuzzing already turned up a number of issues including a security bug in GnuPG.
