[MediaWiki-announce] Security Release: 1.25.3, 1.24.4 and 1.23.11

I would like to announce the release of MediaWiki 1.25.3, 1.24.4, and 1.23.11. These releases fix five security issues in core, in addition to other bug fixes. Download links are given at the end of this email == Security fixes == * Wikipedia user RobinHood70 reported two issues in the chunked upload API. The API failed to correctly stop adding new chunks to the upload when the reported size was exceeded (T91203), allowing a malicious users to upload add an infinite number of chunks for a single file upload. Additionally, a malicious user could upload chunks of 1 byte for very large files, potentially creating a very large number of files on the server's filesystem (T91205). <https://phabricator.wikimedia.org/T91203> <https://phabricator.wikimedia.org/T91205> * Internal review discovered that it is not possible to throttle file uploads. <https://phabricator.wikimedia.org/T91850> * Internal review discovered a missing authorization check when removing suppression from a revision. This allowed users with the 'viewsuppressed' user right but not the appropriate 'suppressrevision' user right to unsuppress revisions. <https://phabricator.wikimedia.org/T95589> * Richard Stanway from teamliquid.net reported that thumbnails of PNG files generated with ImageMagick contained the local file path in the image metadata. <https://phabricator.wikimedia.org/T108616> == Bug Fixes in 1.25.3 == * Fix having multiple callbacks for a single hook. <https://phabricator.wikimedia.org/T98975> * maintenance/refreshLinks.php did not always remove all links pointing to nonexistent pages. <https://phabricator.wikimedia.org/T107632> * $wgEmergencyContact and $wgPasswordSender now use their default value if set to an empty string. <https://phabricator.wikimedia.org/T104142> * Provide fallbacks for use of mb_convert_encoding() in HtmlFormatter. It was causing an error when accessing the api help page if the mbstring PHP extension was not installed. <https://phabricator.wikimedia.org/T62174> * Confirmation emails would sometimes contain invalid codes. <https://phabricator.wikimedia.org/T105896> * Fixed edit stash inclusion queries. <https://phabricator.wikimedia.org/T105597> == Bug Fixes in 1.24.4 == * Minimal PSR-3 debug logger to support backports from 1.25+. <https://phabricator.wikimedia.org/T91653> * Fix indexing of moved pages with PostgreSQL. Requires running update.php to fix. <https://phabricator.wikimedia.org/T68650> == Release notes == Full release notes for 1.25.3: <https://www.mediawiki.org/wiki/Release_notes/1.25> Full release notes for 1.24.4: <https://www.mediawiki.org/wiki/Release_notes/1.24> Full release notes for 1.23.11: <https://www.mediawiki.org/wiki/Release_notes/1.23> For information about how to upgrade, see <https://www.mediawiki.org/wiki/Manual:Upgrading> ********************************************************************** 1.25.3 ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.25/mediawiki-1.25.3.tar.gz https://releases.wikimedia.org/mediawiki/1.25/mediawiki-core-1.25.3.tar.gz Patch to previous version: https://releases.wikimedia.org/mediawiki/1.25/mediawiki-1.25.3.patch.gz https://releases.wikimedia.org/mediawiki/1.25/mediawiki-i18n-1.25.3.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.25/mediawiki-1.25.3.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.25/mediawiki-1.25.3.patch.gz.sig https://releases.wikimedia.org/mediawiki/1.25/mediawiki-core-1.25.3.tar.gz.… https://releases.wikimedia.org/mediawiki/1.25/mediawiki-i18n-1.25.3.patch.g… Public keys: https://www.mediawiki.org/keys/keys.html ********************************************************************** 1.24.4 ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.24/mediawiki-1.24.4.tar.gz https://releases.wikimedia.org/mediawiki/1.24/mediawiki-core-1.24.4.tar.gz Patch to previous version: https://releases.wikimedia.org/mediawiki/1.24/mediawiki-1.24.4.patch.gz https://releases.wikimedia.org/mediawiki/1.24/mediawiki-i18n-1.24.4.patch.gz GPG signatures: https://releases.wikimedia.org/mediawiki/1.24/mediawiki-1.24.4.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.24/mediawiki-1.24.4.patch.gz.sig https://releases.wikimedia.org/mediawiki/1.24/mediawiki-core-1.24.4.tar.gz.… https://releases.wikimedia.org/mediawiki/1.24/mediawiki-i18n-1.24.4.patch.g… Public keys: https://www.mediawiki.org/keys/keys.html ********************************************************************** 1.23.11 ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.23/mediawiki-1.23.11.tar.gz https://releases.wikimedia.org/mediawiki/1.23/mediawiki-core-1.23.11.tar.gz Patch to previous version: https://releases.wikimedia.org/mediawiki/1.23/mediawiki-1.23.11.patch.gz https://releases.wikimedia.org/mediawiki/1.23/mediawiki-i18n-1.23.11.patch.… GPG signatures: https://releases.wikimedia.org/mediawiki/1.23/mediawiki-1.23.11.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.23/mediawiki-1.23.11.patch.gz.sig https://releases.wikimedia.org/mediawiki/1.23/mediawiki-core-1.23.11.tar.gz… https://releases.wikimedia.org/mediawiki/1.23/mediawiki-i18n-1.23.11.patch.… Public keys: https://www.mediawiki.org/keys/keys.html -Chad
