I would like to announce the release of MediaWiki 1.29.2, 1.28.3 and 1.27.4! These releases fix nine security issues in core and one related issue in the vendor folder. Download links are given at the end of this email. Patches will be pushed to gerrit after this email is sent, and will land into the relevant branches as fast as our CI infrastructure allows. Git tags will follow soon after. All related tasks will be made public in phabricator too in the following few hours. Please note that this month is the End-Of-Life date for MediaWiki 1.28. This means that MediaWiki 1.28.3 will be the last security release for that version, barring any unforeseen issues. We would strongly encourage users of MediaWiki 1.28 to upgrade to MediaWiki 1.29, released in July 2017, or a yet newer version as soon as possible. MediaWiki 1.29 will be supported until July 2018. See <https://www.mediawiki.org/wiki/Version_lifecycle> for more information. This release also serves as a maintenance release for these branches. == Security fixes == * (T128209) Reflected File Download from api.php. Reported by Abdullah Hussam. (CVE-2017-8809) * (T165846) BotPasswords doesn't throttle login attempts. * (T134100) On private wikis, login form shouldn't distinguish between login failure due to bad username and bad password. (CVE-2017-8810) * (T178451) XSS when $wgShowExceptionDetails = false and browser sends non-standard url escaping. (CVE-2017-8808) * (T176247) It's possible to mangle HTML via raw message parameter expansion. (CVE-2017-8811) * (T125163) id attribute on headlines allow raw >. (CVE-2017-8812) * (T124404) language converter can be tricked into replacing text inside tags by adding a lot of junk after the rule definition. (CVE-2017-8814) * (T119158) Language converter: unsafe attribute injection via glossary rules (CVE-2017-8815) The following only affects 1.29: * (T180488) (T125177) "api.log contains passwords in plaintext" wasn't correctly fixed in all branches in the previous security release. (CVE-2017-0361) The following only affects 1.27 and 1.28: * (T180231) composer.json has require-dev versions of PHPUnit with known security issues. Reported by Tom Hutchison. (CVE-2017-9841) It is recommended to run `composer update --no-dev` after upgrading to MW 1.27.4 or 1.28.3 if you installed MediaWiki via git. If you are using the tarball, you are not affected, and you do not need to run this command. This will remove developer dependancies that production wikis do not require. If you require developer dependancies, run `composer update` which will update to a version of PHPUnit without known RCE. If you cannot run `composer update` for any reason, it is recommended that you delete the offending file as a minimum yourself using the following command: `rm -rf vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php` == Links to all mentioned tasks == https://phabricator.wikimedia.org/T128209 https://phabricator.wikimedia.org/T165846 https://phabricator.wikimedia.org/T134100 https://phabricator.wikimedia.org/T178451 https://phabricator.wikimedia.org/T176247 https://phabricator.wikimedia.org/T125163 https://phabricator.wikimedia.org/T180231 https://phabricator.wikimedia.org/T125163 https://phabricator.wikimedia.org/T124404 https://phabricator.wikimedia.org/T119158 https://phabricator.wikimedia.org/T180488 https://phabricator.wikimedia.org/T125177 == Release notes == Full release notes for 1.27.4: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_27/RELEASE-NOTES-1.27 https://www.mediawiki.org/wiki/Release_notes/1.27 Full release notes for 1.28.3: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_28/RELEASE-NOTES-1.28 https://www.mediawiki.org/wiki/Release_notes/1.28 Full release notes for 1.29.2: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_29/RELEASE-NOTES-1.29 https://www.mediawiki.org/wiki/Release_notes/1.29 For information about how to upgrade, see <https://www.mediawiki.org/wiki/Manual:Upgrading> ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.27/mediawiki-1.27.4.tar.gz Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.27/mediawiki-core-1.27.4.tar.gz Patch to previous version (1.27.3): https://releases.wikimedia.org/mediawiki/1.27/mediawiki-1.27.4.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.27/mediawiki-core-1.27.4.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.27/mediawiki-1.27.4.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.27/mediawiki-1.27.4.patch.gz.sig Public keys: https://www.mediawiki.org/keys/keys.html ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.28/mediawiki-1.28.3.tar.gz Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.28/mediawiki-core-1.28.3.tar.gz Patch to previous version (1.28.2): https://releases.wikimedia.org/mediawiki/1.28/mediawiki-1.28.3.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.28/mediawiki-core-1.28.3.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.28/mediawiki-1.28.3.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.28/mediawiki-1.28.3.patch.gz.sig Public keys: https://www.mediawiki.org/keys/keys.html ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.29/mediawiki-1.29.2.tar.gz Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.29/mediawiki-core-1.29.2.tar.gz Patch to previous version (1.29.1): https://releases.wikimedia.org/mediawiki/1.29/mediawiki-1.29.2.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.29/mediawiki-core-1.29.2.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.29/mediawiki-1.29.2.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.29/mediawiki-1.29.2.patch.gz.sig Public keys: https://www.mediawiki.org/keys/keys.html
