{"schemaVersion":3,"id":"MGASA-2014-0113","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Updated mediawiki packages fix security vulnerabilities\n\nMediaWiki user Michael M reported that the fix for CVE-2013-4568 allowed\ninsertion of escaped CSS values which could pass the CSS validation checks,\nresulting in XSS (CVE-2013-6451).\n\nChris from RationalWiki reported that SVG files could be uploaded that\ninclude external stylesheets, which could lead to XSS when an XSL was used\nto include JavaScript (CVE-2013-6452).\n\nDuring internal review, it was discovered that MediaWiki's SVG sanitization\ncould be bypassed when the XML was considered invalid (CVE-2013-6453).\n\nDuring internal review, it was discovered that MediaWiki displayed some\ninformation about deleted pages in the log API, enhanced RecentChanges, and\nuser watchlists (CVE-2013-6472).\n\nNetanel Rubin from Check Point discovered a remote code execution\nvulnerability in MediaWiki's thumbnail generation for DjVu files. Internal\nreview also discovered similar logic in the PdfHandler extension, which\ncould be exploited in a similar way (CVE-2014-1610).\n\nMediaWiki has been updated to version 1.22.2, which fixes these issues, as\nwell as several others.\n\nAlso, the mediawiki-ldapauthentication and mediawiki-math extensions have\nbeen updated to newer versions that are compatible with MediaWiki 1.22.\n\nAdditionally, the mediawiki-graphviz extension has been obsoleted, due to\nthe fact that it is unmaintained upstream and is vulnerable to cross-site\nscripting attacks.\n\nNote: if you were using the \"instances\" feature in these packages to\nsupport multiple wiki instances, this feature has now been removed.  You\nwill need to maintain separate wiki instances manually.","dates":{"published":"2014-03-02T20:53:30.000Z","modified":"2026-04-16T06:22:54.196Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"mediawiki","name":"mediawiki","label":"mediawiki","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/mediawiki","purlType":"rpm","versions":[{"text":"<
