LibreOffice leverages Google’s OSS-Fuzz to improve quality of office suite

Berlin, May 23, 2017 – For the last five months, The Document Foundation has made use of OSS-Fuzz, Google’s effort to make open source software more secure and stable, to further improve the quality and reliability of LibreOffice’s source code. Developers have used the continuous and automated fuzzing process, which often catches issues just hours after they appear in the upstream code repository, to solve bugs – and potential security issues – before the next binary release.

LibreOffice is the first free office suite in the marketplace to leverage Google’s OSS-Fuzz. The service, which is associated with other source code scanning tools such as Coverity, has been integrated into LibreOffice’s security processes – under Red Hat’s leadership – to significantly improve the quality of the source code.

According to Coverity Scan’s last report, LibreOffice has an industry leading defect density of 0.01 per 1,000 lines of code (based on 6,357,292 lines of code analyzed on May 15, 2017). “We have been using OSS-Fuzz, like we use Coverity, to catch bugs – some of which may turn into security issues – before the release. So far, we have been able to solve all of the 33 bugs identified by OSS-Fuzz well in advance over the date of disclosure”, says Red Hat’s Caolán McNamara, a senior developer and the leader of the security team at LibreOffice.

Additional information about Google OSS-Fuzz is available on the project’s homepage on GitHub – https://github.com/google/oss-fuzz – and on Google Open Source Blog: (1) https://opensource.googleblog.com/2016/12/announcing-oss-fuzz-continuous-fuzzing.html (announcement), and (2) https://opensource.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html (results after five months).

Month of LibreOffice, May 2017: Printed stickers are here!

We’re 17 days into the Month of LibreOffice, May 2017 – and we’ve just gone over the 200 stickers mark. Yes, that’s 200 community members who’ve helped out with code, QA, translations, documentation, user support and marketing – and each one will receive a cool sticker for their laptops and other kit. Thanks everyone for your help!

Also, the printed stickers arrived at The Document Foundation today:

There are still two more weeks of the Month of LibreOffice to go – so don’t miss out on a sticker! Read on to find out how you can help the project (and millions of LibreOffice users around the world), and claim a sticker for yourself:

How to get a sticker

There are many ways you can help the LibreOffice project and claim a sticker:

  • Help to confirm bugs: go to our Bugzilla page and look for new bugs. If you can recreate one, add a comment like “CONFIRMED on Windows 10 and LibreOffice 5.3.2”. (Make sure you’re using the latest version of LibreOffice.)
  • Contribute code: The codebase is big, but there are lots of places to get involved with small jobs. See our Developers page on the website and this page on the wiki to get started. Once you’ve submitted a patch, if it gets merged we’ll send you a sticker!
  • Translate the interface: LibreOffice is available in a wide range of languages, but its interface translations need to be kept up-to-date. Or maybe you want to translate the suite to a whole new language? Get involved here.
  • Write documentation: Another way to earn a badge is to help the LibreOffice documentation team. Whether you want to update the online help or add chapters to the handbooks, here’s where to start.
  • Answer questions from users: Over on Ask LibreOffice there are many users looking for help with the suite. We’re keeping an eye on that site so if you give someone useful advice, you can claim a shiny sticker.
  • Spread the word: Tell everyone about LibreOffice on Twitter! Just say why you love it or what you’re using it for, add the #libreoffice hashtag, and at the end of the month you can claim a sticker. (We have a maximum of 100 stickers for this category, in case the whole internet starts tweeting!)

Video interview: Florian Effenberger, Executive Director at TDF

Florian is one of the founders of The Document Foundation (TDF), the charitable entity behind LibreOffice. He’s also TDF’s Executive Director, overseeing a small team that works on release building, documentation, QA, design and marketing for LibreOffice. In this interview, he explains how TDF is structured, how it’s funded, and how the money is used.

LibreOffice on social media: stats for June 2016 – April 2017

To help spread the word about LibreOffice and get feedback from users (and contributors), The Document Foundation operates various social media accounts. Some of these have been running since the start of the project – while others are relatively new. We’ve been collecting statistics about our social media accounts for a while, so let’s share them with the world.

 

Twitter

Our Twitter account is used mainly for announcements, links to blog posts and videos, and retweeting interesting messages from LibreOffice users. We sometimes get questions as well, although it’s hard to provide long answers in 140 characters, so we often point users at Ask LibreOffice instead. Here’s our follower count in recent months:

 

Facebook

Meanwhile, our English-language Facebook page is getting busier, and via it we receive lots of messages of support (along with requests for new features). The audience tends to be made up of end-users rather than developers, although we encourage people to get involved with non-coding tasks such as translations, testing and documentation. This graph shows the growth in page likes over the last 11 months:

 

Google+

We also have a Google+ page, which isn’t as busy as Facebook, but our followers there tend to be more technical – so it’s a great place to bring in potential contributors. In terms of followers, the growth here over the last 11 months hasn’t been huge, but there’s steady progress:

 

YouTube

We’ve been tracking the total number of video views on our YouTube channel since November 2016. Due to the new content we’ve been adding, including new features videos, interviews and tutorials in many languages (thanks to our worldwide community), the total view count has shot up:

 

Others

The LibreOffice community on Reddit is quite small, but we’re posting regular updates and encouraging users to help one another with questions. Then there’s our Telegram group which we launched late last year – this has reached almost 400 members.

Finally, if you think LibreOffice and/or The Document Foundation should be active on some other social media that we’ve not covered in this post, join our marketing community and let us know!
