 Mandriva Linux Security Advisory                         MDVSA-2015:200
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : mediawiki
 Date    : April 10, 2015
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Updated mediawiki packages fix security vulnerabilities:
 
 In MediaWiki before 1.23.9, one could circumvent the SVG MIME blacklist
 for embedded resources. This allowed an attacker to embed JavaScript
 in the SVG (CVE-2015-2931).
 
 In MediaWiki before 1.23.9, the SVG filter to prevent injecting
 JavaScript using animate elements was incorrect (CVE-2015-2932).
 
 In MediaWiki before 1.23.9, a stored XSS vulnerability exists due
 to the way attributes were expanded in MediaWiki's Html class, in
 combination with LanguageConverter substitutions (CVE-2015-2933).
 
 In MediaWiki before 1.23.9, MediaWiki's SVG filtering could be bypassed
 with entity encoding under the Zend interpreter. This could be used
 to inject JavaScript (CVE-2015-2934).
 
 In MediaWiki before 1.23.9, one could bypass the style filtering for
 SVG files to load external resources. This could violate the anonymity
 of users viewing the SVG (CVE-2015-2935).
 
 In MediaWiki before 1.23.9, MediaWiki versions using PBKDF2 for
 password hashing (not the default for 1.23) are vulnerable to DoS
 attacks using extremely long passwords (CVE-2015-2936).
 
 In MediaWiki before 1.23.9, MediaWiki is vulnerable to Quadratic
 Blowup DoS attacks, under both HHVM and Zend PHP (CVE-2015-2937).
 
 In MediaWiki before 1.23.9, the MediaWiki feature allowing a user to
 preview another user's custom JavaScript could be abused for privilege
 escalation (CVE-2015-2938).
 
 In MediaWiki before 1.23.9, function names were not sanitized in Lua
 error backtraces, which could lead to XSS (CVE-2015-2939).
 
 In MediaWiki before 1.23.9, the CheckUser extension did not prevent
 CSRF attacks on the form allowing checkusers to look up sensitive
 information about other users. Since the use of CheckUser is logged,
 the CSRF could be abused to defame a trusted user or flood the logs
 with noise (CVE-2015-2940).
 
 The mediawiki package has been updated to version 1.23.9, fixing
 these issues and other bugs.
