Updated mediawiki packages fix security vulnerabilities:

In MediaWiki before 1.23.12, an XSS vector exists when MediaWiki is configured with a non-standard configuration, from wikitext when $wgArticlePath='$1' (CVE-2015-8622).

In MediaWiki before 1.23.12, tokens were being compared as strings, which could allow a timing attack (CVE-2015-8623, CVE-2015-8624).

In MediaWiki before 1.23.12, parameters passed to the curl library were not sanitized, which could cause curl to upload files from the webserver to an attacker when POST variable starts with '@' (CVE-2015-8625).

In MediaWiki before 1.23.12, the password reset token could be shorter than the minimum required password length (CVE-2015-8626).

In MediaWiki before 1.23.12, blocking IP addresses with zero-padded octets resulted in a failure to block the IP address (CVE-2015-8627).

In MediaWiki before 1.23.12, a combination of Special:MyPage redirects and pagecounts allows an external site to know the wikipedia login of an user (CVE-2015-8628).
