This update brings mediawiki to version 1.16.4, which is the latest stable release at the moment, but currently also the only supported and recommended release by the mediawiki developer community.

Further changes :

  - some simple wiki management functionality was added :

    - mw-createinstance <path> creates a wiki instance under       <path>, which is autoupgraded upon package updates.

  - any wiki path entered in /etc/mediawiki/instances will     be autoupgraded upon package updates.

  - /var/www/wiki is entered into this list automatically,     but you can remove it if you don't want this instance to     be autoupgraded.

  - opensearch and suggestions are enabled by default

    - several bug fixes (see changelog).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

There is a cross-site scripting vulnerability in this installation of MediaWiki that may allow an attacker to execute arbitrary script code in the browser of an unsuspecting user.  Such script code could steal authentication credentials and be used to launch other attacks.

This version of MediaWiki also contains a local file inclusion vulnerability that is exploitable when running Microsoft Windows, but this plugin did not test for that vulnerability.

Medawiki reports :

An arbitrary script inclusion vulnerability was discovered. The vulnerability only allows execution of files with names ending in '.php' which are already present in the local filesystem. Only servers running Microsoft Windows and possibly Novell Netware are affected.
Despite these mitigating factors, all users are advised to upgrade, since there is a risk of complete server compromise. MediaWiki 1.8.0 and later is affected.

Security researcher mghack discovered a CSS injection vulnerability.
For Internet Explorer and similar browsers, this is equivalent to an XSS vulnerability, that is to say, it allows the compromise of wiki user accounts. For other browsers, it allows private data such as IP addresses and browsing patterns to be sent to a malicious external web server. It affects all versions of MediaWiki. All users are advised to upgrade.
