MGASA-2014-0113 - Updated mediawiki packages fix security vulnerabilities Publication date: 02 Mar 2014 URL: Type: security Affected Mageia releases: 3, 4 CVE: CVE-2013-6451, CVE-2013-6452, CVE-2013-6453, CVE-2013-6472, CVE-2014-1610 Description: MediaWiki user Michael M reported that the fix for CVE-2013-4568 allowed insertion of escaped CSS values which could pass the CSS validation checks, resulting in XSS (CVE-2013-6451). Chris from RationalWiki reported that SVG files could be uploaded that include external stylesheets, which could lead to XSS when an XSL was used to include JavaScript (CVE-2013-6452). During internal review, it was discovered that MediaWiki's SVG sanitization could be bypassed when the XML was considered invalid (CVE-2013-6453). During internal review, it was discovered that MediaWiki displayed some information about deleted pages in the log API, enhanced RecentChanges, and user watchlists (CVE-2013-6472). 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). MediaWiki has been updated to version 1.22.2, which fixes these issues, as well as several others. Also, the mediawiki-ldapauthentication and mediawiki-math extensions have been updated to newer versions that are compatible with MediaWiki 1.22. Additionally, the mediawiki-graphviz extension has been obsoleted, due to the fact that it is unmaintained upstream and is vulnerable to cross-site scripting attacks. Note: if you were using the "instances" feature in these packages to support multiple wiki instances, this feature has now been removed. You will need to maintain separate wiki instances manually.
