Title:	MediaWiki Multiple Vulnerabilities (Mar 2015) - Linux
Summary:	MediaWiki is prone to multiple vulnerabilities.
Description:	Summary: MediaWiki is prone to multiple vulnerabilities. Vulnerability Insight: Multiple flaws exist due to: - incomplete blacklist vulnerability in includes/upload/UploadBase.php allows remote attackers to inject arbitrary web script or HTML via an application/xml MIME type for a nested SVG with a data: URI. - incomplete blacklist vulnerability allows remote attackers to inject arbitrary web script or HTML via an animated href XLink element. - MediaWiki does not properly handle when the Zend interpreter xml_parse function does not expand entities, which allows remote attackers to inject arbitrary web script or HTML via a crafted SVG file. - bypassing the SVG filtering and obtain sensitive user information via a mixed case @import in a style element in an SVG file. - when using HHVM or Zend PHP, allows remote attackers to cause a denial of service ('quadratic blowup' and memory consumption) via an XML file containing an entity declaration with long replacement text and many references to this entity, a different vulnerability than CVE-2015-2942. - Cross-site scripting (XSS) vulnerability allowing remote attackers to inject arbitrary web script or HTML via a custom JavaScript file, which is not properly handled when previewing the file. - Cross-site scripting (XSS) vulnerability, when using HHVM, allows remote attackers to inject arbitrary web script or HTML via an invalid parameter in a wddx format request to api.php, which is not properly handled in an error message, related to unsafe calls to wddx_serialize_value. - when using HHVM, allows remote attackers to cause a denial of service (CPU and memory consumption) via a large number of nested entity references in an (1) SVG file or (2) XMP metadata in a PDF file, aka a 'billion laughs attack', a different vulnerability than CVE-2015-2937. Vulnerability Impact: Successful exploitation will allow remote attackers to conduct XSS attacks, gain access to sensitive information and have other some unspecified impact. Affected Software/OS: MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2 Solution: Upgrade to version 1.19.24 or 1.23.9 or 1.24.2 or later.
