    Summary: Updated mediawiki packages fix security vulnerabilities

    Details: Updated mediawiki packages fix security vulnerabilities: In MediaWiki before 1.23.8, thumb.php outputs wikitext message as raw HTML, which could lead to cross-site scripting. Permission to edit MediaWiki namespace is required to exploit this. In MediaWiki before 1.23.8, a malicious site can bypass CORS restrictions in $wgCrossSiteAJAXdomains in API calls if it only included an allowed domain as part of its name.
