I would like to announce the release of MediaWiki 1.29.2, 1.28.3 and 1.27.4!
These releases fix eight security issues in core and one related issue in the vendor
folder. Download links are given at the end of this email.
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. (CVE-2017-)
* (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-)
* (T124404) language converter can be tricked into replacing text inside tags by
adding a lot of junk after the rule definition. (CVE-2017-)
* (T119158) Language converter: unsafe attribute injection via glossary rules (CVE-2017-)
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. 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`
