ClusterFuzz is a scalable fuzzing infrastructure that finds security and stability issues in software.

Last update: Jan 08, 2023

Overview

ClusterFuzz

ClusterFuzz is a scalable fuzzing infrastructure that finds security and stability issues in software.

Google uses ClusterFuzz to fuzz all Google products and as the fuzzing backend for OSS-Fuzz.

ClusterFuzz provides many features which help seamlessly integrate fuzzing into a software project's development process:

Highly scalable. Can run on any size cluster (e.g. OSS-Fuzz instance runs on 100,000 VMs).
Accurate deduplication of crashes.
Fully automatic bug filing, triage and closing for various issue trackers (e.g. Monorail, Jira).
Supports multiple coverage guided fuzzing engines (libFuzzer, AFL, AFL++ and Honggfuzz) for optimal results (with ensemble fuzzing and fuzzing strategies).
Support for blackbox fuzzing.
Testcase minimization.
Regression finding through bisection.
Statistics for analyzing fuzzer performance, and crash rates.
Easy to use web interface for management and viewing crashes.
Support for various authentication providers using Firebase.

Update TensorFlow and other dependencies after Python3 migration

We haven't updated it in a while and while working on https://github.com/google/clusterfuzz/issues/1535 it became evident that we're using a too old version. For instance, there is not build of it for Python3.7.

I'm hoping to fix https://github.com/google/clusterfuzz/issues/1535 with some old-but-new-enough version, but we'll definitely should upgrade all ML pieces after the migration.

Gradientfuzz Integration [2]
Added GradientFuzz training task script.

Functionality: Generates input/output pairs from raw inputs, trains model, and uploads weights to GCS.

Added GradientFuzz training task unit tests.

Tests mock function calls, input/output pair generation, and training on a small corpus using a small, custom-built binary.

Added auxiliary test files for unit tests.

Refactored functions from RNN generator training script for general ML-fuzz training scripts.

Convert to TF v2 model

I had to change batch size: now it must be the same as when the model was created. I think there might a possibility to use a different batch size but I'll have to look through documentation to make sure.

Also, changed a typo: first argument of build_model should be the product between hidden layer size and hidden state size, not the square of one of the sizes. Again, this should match the model as trained.

Finally, changed the error type that is thrown when trying to predict using a model of invalid format.

The rest, is just moving stuff outside of the session loop and replacing the feed+run with a direct model call to get the prediction.

libFuzzer: use two step merge after fuzzing for accurate stats (#802).
Use the two step merge process implemented and documented in https://reviews.llvm.org/D66107

Parse edge and feature coverage from the merge log. The first merge step is done using the initial corpus only, i.e. it gives the "initial" stats. The second merge step is executed on the newly generated files and provides the overall stats (coverage data is appended to the "initial" corpus, that's why we need to specify the same -merge_control_file for two steps_. The diff between two stats is supposed to be the most accurate data we can obtain.

This implementation runs libFuzzer's merge in a way that prioritizes reduced inputs over the longer equivalents from the original corpus. We might be able to get rid of move_mergeable_units, I'll look into that later, once this change settles in.

libFuzzer on all platforms / projects should be recent enough at this point, therefore I've recompiled the test fuzzers as well to include that new merge functionality.

I'll try to stage this on a bot tomorrow as it feels a little scary, even though tests were extremely helpful and caught a few mistakes I made.

Add support for Android Cuttlefish flash

This change is based on the new design that Clusterfuzz and Cuttlefish will be started in separate docker containers under same network. To flash the device, Clusterfuzz will fetch the latest Cuttlefish builds from Android build system and launch the cvd on Cuttlefish via ssh.

Use Filestore NFS rather than GCS in Google Cloud?

So we are using Clusterfuzz but we are finding that the vast majority of cost of using clusterfuzz in Google cloud is going to class B operations in GCS. with about 100 bots we are finding that half the cost is going into GCS class B read operations (aout 3-4 Billion operations), which comes out to about $1500 in read operations out of a total of $3000/month. We want to ramp up the number of bots to about 1000 VMs but the expected increase in read operations would break our budget.

So we decided to also setup an on-premise clusterfuzz (cfz) instance but of course that has it's own challenges. But we realized that on-prem local instance of cfz uses a GCS emulator with an NFS backend. I was wondering if a cloud production deployment of Clusterfuzz has used the GCS emulator to point to Google Filestore so that we can avoid the high cost of GCS class B operations.

This could help mitigate the high cost of all the read operations from GCS and save us 50% in costs? Has anyone tried this and do you see any problems attempting this? Is there anything we lose by doing this? Do we lose any of the functionality of the analytics?

Is this even possible with the cloud version of clusterfuzz? If so any guidance would be helpful.

Document port forwarding for 900*, maybe other ports if server accessed from remote.

I'm running a local instance of clusterfuzz. I just run the server with default settings.

Then I follows this guide https://google.github.io/clusterfuzz/setting-up-fuzzing/libfuzzer-and-afl/ ,

I can "add new job". But it failed if I upload custom fuzzer zip to the job.

Initial support for Fuchsia on ClusterFuzz.
Feedback/changes very welcome.

This CL teaches ClusterFuzz to spin up a Fuchsia QEMU VM and communicate with it in a basic way.

Right now, all the "fuzzing" command does is run "ls" on the target system, as a sort of "hello world"; a follow-up CL will teach it to select & use proper fuzzing commands.

We chose this approach because Fuchsia fully supports libfuzzer on-target; running, e.g., "fuzz [fuzzer_name]" instead of "ls" will simply fuzz using the named fuzzer, and return when it encounters some result. See https://fuchsia.googlesource.com/fuchsia/+/refs/heads/master/docs/development/workflows/libfuzzer.md

Follow-on CLs will include: using "fuzz" instead of "ls", syncing corpora, perhaps utilizing GCE support in lieu of QEMU, etc

To run this locally, you must:

Use the admin panel to set up a Fuchsia fuzzing "job". -> The job must have Platform = FUCHSIA -> The job must use the libfuzzer and engine_asan templates -> You must include a libfuzzer_asan_test_fuzzer.zip file in "Custom Build" --> (I noticed that jobs tended to hang with 'Upto #' statements if a custom build was not included; would love to find some workaround for this, since the Fuchsia fuzzing job doesn't really need a custom build.) -> Finally, set FUCHSIA-RESOURCES_PATH to a proper GCS bucket path. You can use mine for testing if you like: gs://fuchsia_on_clusterfuzz_resources_v1/*

Go to "Fuzzers" in the admin panel and add your job to the libFuzzer fuzzer.

Run QUEUE_OVERRIDE=FUCHSIA OS_OVERRIDE=FUCHSIA python butler.py run_bot --name someplace ~/someplace.

For debugging, it's helpful to tail -f ~/someplace/clusterfuzz/bot/logs*.

I've attempted to fuzz some simple C programs using Clusterfuzz which i'm hosting on GCP. I wasn't able to produce any output so I decided to restart the service. Now I am receiving errors related to cron jobs that run regularly throughout the day, despite there not being any currently running fuzzing tasks.

1) RuntimeError: Invalid subscription: projects/clusterfuzz-XXXXX/subscriptions/jobs-linux 2) Task exited with exception. main 3) Failed to get any fuzzing tasks. This should not happen. get_task 4) RuntimeError: Invalid topic: projects/clusterfuzz-XXXXX/topics/jobs-linux

tsan_suppressions.txt not in repository

Test cases like https://clusterfuzz.com/testcase-detail/6560743240695808 use TSAN_OPTIONS and refer to a tsan_suppressions.txt file at: /mnt/scratch0/clusterfuzz/src/appengine/config/suppressions/tsan_suppressions.txt

There appears to be no such file in https://github.com/google/clusterfuzz/tree/master/src/appengine

We'd like to either change the file and include a suppression for V8 from https://source.chromium.org/chromium/chromium/src/+/main:v8/tools/sanitizers/tsan_suppressions.txt - or find a way to use the latter directly. E.g. by using an environment variable.

It seems that https://github.com/google/clusterfuzz/blob/4e1f65d3579cd835fd3bf6758d852f7780997a20/src/clusterfuzz/_internal/system/environment.py#L389 offers a CONFIG_DIR_OVERRIDE. If we specify a value at the job level, how can we make it point to the absolute APP_DIR ? If that was possible, we'd bundle a folder config/suppressions/ together with V8.
