LibreOffice 3.5.1 provides additional security and stability

Berlin, March 15, 2012 – The Document Foundation announces LibreOffice 3.5.1, the second version of the 3.5 family, targeting private individuals and enterprises. LibreOffice 3.5.1 fixes the majority of the most-important bugs identified by users and is expected to be appealing for most enterprises. TDF encourages large organizations to deploy LibreOffice in conjunction with a support partner, who can assess specific requirements, help manage migration and provide bespoke fixes for identified issues. Purchasing LibreOffice support from a TDF partner provides enterprises with an indirect means to contribute financially to the project, to fund software development, to improve the stability and accelerate the growth. “During the last month, the number of TDF hackers has overtaken the threshold of 400 code developers, with a large majority of independent volunteers and several companies paying full time hackers. In any case, the project is independent, as none of these companies employs more than 7% of the developers”, affirms Italo Vignoli, member of the Board of Directors. “Since September 2010, a monthly average of 20 new hackers has joined the project, attracted by the copyleft license, the lack of copyright assignment and a welcoming environment”. LibreOffice 3.5.1 is available for immediate download from the following

The Document Foundation publishes details of LibreOffice 3.4.3 security fixes

The Internet, October 4, 2011 – The Document Foundation (TDF) publishes some details of the security fixes included with the recently released LibreOffice 3.4.3, and included in the older 3.3.4 version. Following industry best practice, details of security fixes are withheld until users have been given time to migrate to the new version. RedHat security researcher Huzaifa Sidhpurwala identified a memory corruption vulnerability in the code responsible for loading Microsoft Word documents in LibreOffice. This flaw could have been used for nefarious purposes, such as installing viruses, through a specially-crafted file. The corresponding vulnerability description is CVE-2011-2713,”Out-of-bounds property read in binary .doc filter”. LibreOffice 3.4.3 also includes various improvements to the loading of Windows Metafile (.wmf) and Windows Enhanced Metafile (.emf) image formats that were found through fuzz testing. LibreOffice developers have developed some additional security patches and fixes. These are part of a general set of development improvements which are reflected in the overall quality and stability of the software. Most LibreOffice 3.4.3 security fixes have been developed by Caolan McNamara of RedHat and Marc-André Laverdière of Tata Consultancy Services. “Working on fuzzing LibreOffice import filters has been a great experience, and I am glad I could contribute in

Migrating small businesses to LibreOffice and Linux

We often talk on this blog about large-scale migrations to LibreOffice, such as in the Austrian Military. But many small businesses are switching away from Microsoft, Google and other tech giants too. Today we’re talking to Mišo Oroz from Zerolock, a company in Italy that helps small businesses to switch to free and open source software (FOSS): Tell us a bit about what you do Zerolock is an IT company I founded in early 2026, based in Spirano, near Bergamo, in Lombardy. The focus is simple: migrating small businesses with 2 to 20 office workstations from proprietary systems to fully open source infrastructure. We use Linux workstations with KDE Plasma as the desktop environment, LibreOffice as the office suite, and a full stack of open source tools for collaboration, communication and security. Everything is self-hosted – everything is on European servers. There is no Microsoft and no vendor lock-in. What kinds of businesses are you helping to migrate to Linux and LibreOffice, and why do they want to switch? They are mostly non-technical environments: a logistics company, a construction company, a dental practice, a law firm. The trigger is rarely ideology. It is usually a combination of rising software costs,

LibreOffice 26.8.2 improves stability, multimedia and compatibility

Berlin, 29 October 2026 – The Document Foundation announces LibreOffice 26.8.2, the second minor release in the LibreOffice 26.8 family, available for Windows, macOS and Linux. The new version contains around 35 bug fixes, focusing on stability, multimedia playback and compatibility with legacy file formats. Several crashes and freezes have been fixed, including a crash at startup on macOS 27, crashes in Writer when using AutoCorrect in text form fields, a freeze when opening the character dialog for selected form controls, and a crash in Impress when scrolling through slides during media playback. Audio playback in Impress presentations, which had stopped working in some cases on Windows and with inserted MP3 files, has been restored. Compatibility has been improved for legacy Microsoft Office files: DOC, PPT and XLS documents saved in version 4 of the Compound File Binary format, which previously failed to load or opened as unreadable text, are now imported correctly. Calc adds support for Web Query (.iqy) files and fixes a regression introduced in LibreOffice 26.8.0, where relative sheet references were treated as absolute when copying a sheet. Hyphenation has been refined with new options to limit hyphenation near constituent boundaries of compound words, together with the

FOSDEM: FOSS Office DevRoom Call for Papers

We are inviting proposals for talks about “FOSS Office Software and Suites“. Office productivity software is one of the oldest and most interesting FOSS categories packed with developer interest. It is also an area where lots of new solutions are arriving with new desktop, web-based and mobile editors, as well as new underlying libraries and filters appearing. These bring lots of opportunities for meeting up and cross-fertilization of ideas, and innovation as well as code sharing between separate FOSS communities and companies that can rarely come together. The FOSS Office devroom brings these projects together in one place. It is open to developers, contributors, integrators, and users of any FOSS office suite or component. Competing projects and document toolkits are explicitly welcome, as the aim is to provide an overview of the entire sector and identify common problems which cannot be solved alone. We invite talks on topics such as: – Architecture, performance, algorithms, data-structures; – Network protocols for real-time collaboration; – Import and export filters, interoperability, and document rendering fidelity; – Accessibility, localisation, typography and support for complex scripts; – Technical challenges of enterprise Office deployments – AI-assisted features and how to integrate them while preserving user control and
