I would like to announce the release of MediaWiki 1.22.2, 1.21.5 and 1.19.11.

Your MediaWiki installation is affected by a remote code execution vulnerability if you have enabled file upload support for DjVu (natively supported by MediaWiki) or PDF files (in combination with the PdfHandler extension). Neither file type is enabled by default in MediaWiki installations. If you are affected, we strongly urge you to update immediately.

Affected supported versions: All

== Security fixes ==

* Netanel Rubin from Check Point discovered a remote code execution vulnerability in MediaWiki's thumbnail generation for DjVu files. Internal review also discovered similar logic in the PdfHandler extension, which could be exploited in a similar way. (CVE-2014-1610) https://bugzilla.wikimedia.org/show_bug.cgi?id=60339

== Bug Fixes in 1.22.2 == * (bug 58253) Check for very old PCRE versions in installer and updater * (bug 60054) Make WikiPage::$mPreparedEdit public
