Some of the referenced Phabricator tasks above _may_ still be private. Unfortunately, when security issues are reported, sometimes sensitive information is exposed and since Phabricator is historical, we cannot make these tasks public without exposing this sensitive information. If you have any additional questions or concerns regarding this update, please feel free to contact security(a)wikimedia.org or file a security task within Phabricator [3].

Maintenance release: 1.31.12

by Sam Reed

The 1.31.12 version fixes the issue with the backports in the 1.31.11 release. The patches linked here need applying on top of the previous patches for 1.31.11. See the previous email for those patches. The full downloads here contain all the previous fixes from the security and maintenance release. Once again, I apologise for the inconvenience of the issues with the previous release. ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.12.tar.gz Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.12.tar.gz Patch to previous version (1.31.11): https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.12.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.12.tar.gz… https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.12.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.12.patch.gz.sig Public keys: https://www.mediawiki.org/keys/keys.html

Security and maintenance release: 1.31.11 / 1.35.1

by Sam Reed

I would like to announce the release of MediaWiki 1.31.11 and 1.35.1! These releases also serve as a maintenance release for these branches. Numerous fixes have been backported into 1.35, including some for PHP 8.0 support (though we are not declaring full PHP 8.0 support yet). T268894 doesn't apply to MediaWiki 1.31, as the code was added in 1.35. Also, only one of the two fixes of T268938 apply to MediaWiki 1.31, as the code was not added until MediaWiki 1.33. While tarballs have already been uploaded, git tags will follow later on today. An "MediaWiki Extensions Security Release Supplement" email will follow this one. == Security fixes == * (T268894, CVE-2020-35474) SECURITY: Message recentchanges-legend-watchlistexpiry can contain raw html. * (T268917, CVE-2020-35475) SECURITY: Messages userrights-expiry-current and userrights-expiry-none can contain raw html. * (T268938, CVE-2020-35478, CVE-2020-35479) SECURITY: BlockLogFormatter can output raw html. * (T205908, CVE-2020-35477) SECURITY: Unable to change visibility of log entries when MediaWiki:Mainpage uses Special:MyLanguage. * (T120883, CVE-2020-35480) SECURITY: Divergent behavior for contributions and user pages of hidden users and missing users. == Links to all mentioned tasks == * https://phabricator.wikimedia.org/T268894 * https://phabricator.wikimedia.org/T268917 * https://phabricator.wikimedia.org/T268938 * https://phabricator.wikimedia.org/T205908 * https://phabricator.wikimedia.org/T120883 == Release notes == Full release notes for 1.31.11: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_31/RELEASE-NOTES… https://www.mediawiki.org/wiki/Release_notes/1.31 Full release notes for 1.35.1: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_35/RELEASE-NOTES… https://www.mediawiki.org/wiki/Release_notes/1.35 For information about how to upgrade, see <https://www.mediawiki.org/wiki/Manual:Upgrading> ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.11.tar.gz Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.11.tar.gz Patch to previous version (1.31.10): https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.11.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.11.tar.gz… https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.11.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.11.patch.gz.sig Public keys: https://www.mediawiki.org/keys/keys.html ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.1.tar.gz Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.35/mediawiki-core-1.35.1.tar.gz Patch to previous version (1.35.0): https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.1.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.35/mediawiki-core-1.35.1.tar.gz.… https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.1.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.1.patch.gz.sig Public keys: https://www.mediawiki.org/keys/keys.html

Security pre-release announcement: 1.31.11 / 1.35.1

by Sam Reed

Hi all, Tomorrow we will be issuing a security and maintenance release to all supported branches of MediaWiki. The new releases will be: - 1.31.11 - 1.35.1 This will resolve 5 issues in MediaWiki core (1 of which isn't applicable to MediaWiki 1.31 at all), and also includes some fixes previously committed to git, including minor security and hardening patches along with bug fixes included for maintenance reasons. We will make the fixes available in these respective release branches, and also master. Tarballs will be available for the above mentioned point releases as well. A summary of some of the security fixes that have gone into non-bundled MediaWiki extensions will also follow. As per the MediaWiki Version lifecycle [1], November 2020 was the scheduled EOL date for the REL1_34. MediaWiki 1.35.1 will be supported until at least September 2023, and would be the recommended upgrade path for anyone still using 1.34. [1] https://www.mediawiki.org/wiki/Version_lifecycle
