Bugfix release

Collabora Online 3.4.1

Released on November 12, 2018

Bugfix release with minor features

  • Fixed corner cases, when image insertion into document directly from the WOPI host did not work.
  • Changed the user interface a bit for image insertion. Now there is ‘Insert Local Image’ function for inserting image from the device/PC, and there is ‘Insert Image’ function for inserting image from the WOPI host (when the WOPI host is capable of this).
  • Added /hosting/capabilities endpoint to advertise online features to WOPI hosts. Currently there is only one feature, the convert-to endpoint, that can be used to generate thumbnail images of the documents.
  • Handle X-Forwarded-For HTTP header for convert-to feature, which means that the client’s IP address from the X-Forwarded-For value is used when Collabora Online decides to allow or to deny the usage of convert-to feature. All participating IP addresses have to be allowed to use convert-to functionality, for example, the IP address of the reverse-proxy and the actual client. Now the log message is clearer about the reason of denial.
  • The convert-to feature is also enabled for the enabled WOPI hosts.
  • Clean up temporary files that are created during the thumbnail generation by convert-to feature.
  • Performance fixes related to documents with many tracked changes. Now it possible to switch off comment boxes for change-tracking with setting the redlining_as_comments to false in the per_document section of the config file.
  • Added a time limit for badly behaved / huge document load / conversions. By default it is 100 seconds. The default can be changed in the config file, with the limit_load_secs setting in the per_document section.
  • The width of the Font Size dropdown on the top toolbar has been fixed.
  • The Rename Sheet dialog now has the current sheet name in input box.
  • Other small fixes of the user interface on mobile devices

Collabora Online 3.4

Released on October 10, 2018

Highlights of the changes since Collabora Online 3.3

  • Significantly improved interactivity on high latency connections;
  • Considerably improved the mobile experience;
  • Possibility to anonymize the logs if necessary (hiding URLs, document names and usernames);
  • Increased performance of Impress by on-demand loading of the slides in slide sorter;
  • Possibility to use a different service root than the toplevel. If the rules of your organization do not permit running services in the root, you can use a subpath for it, like by setting /IT/CollaboraOnline as the ServiceRoot in the configuration file;
  • Convert-to is now allowed only for the hosts explicitly allowed in the configuration file;
  • Possibility to trigger sharing directly from the document. UI for this is enabled only when the CheckFileInfo contains ‘EnableShare: true’ ;
  • Possibility to insert an image file into document directly from the WOPI host. UI for this is enabled only when the CheckFileInfo contains ‘EnableInsertRemoteImage: true’ ;
  • Various other smaller fixes and improvements, including few crasher fixes.

Collabora Online 3.2.2

Released on May 11, 2018

Bugfix release

Collabora Online 3.2.1

Released on May 3, 2018

Security fix

Releases of Collabora Online, from 3.0 onward release contain a security issue related to Admin Console authentication when in the default configuration (with PAM enabled).

Description of issue:
When the admin_console.enable_pam setting is true, and admin_console.username and admin_console.password settings are empty, it is possible to log on to Admin Console with empty username and password.
Workaround for older versions (3.0 – 3.2)
Check whether you have a user/password set for the Admin Console. If so you are safe, otherwise – disabling PAM will disable the Admin Console: set admin_console.enable_pam to false in /etc/loolwsd/loolwsd.xml

If this line is not present (you upgraded) add:

<enable_pam desc="Enable admin user authentication with PAM" type="bool" default="false">false</enable_pam>

to the <admin_console> section in the config file.

Solution in 3.2.1
Upgrading to this out-of-band release addresses this issue and contains only:

  • Adding a setting to disable the Admin Console (admin_console.enable), by default Admin Console is enabled.
  • Disables fallback password access when PAM is enabled.
  • Disables PAM by default.
  • Disallows empty user/password combinations.
