-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2931 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2932 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2933 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2934 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2935 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2936 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2937 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2938 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2939 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2940 http://advisories.mageia.org/MGASA-2015-0142.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 0a5719c634720b2f09037024a6d92d87 mbs1/x86_64/mediawiki-1.23.9-1.mbs1.noarch.rpm c1e4e0b2eaea6bc47bf1d97af2d8de9d mbs1/x86_64/mediawiki-mysql-1.23.9-1.mbs1.noarch.rpm 305c803833c271e39ae22f8ab5b04db1 mbs1/x86_64/mediawiki-pgsql-1.23.9-1.mbs1.noarch.rpm a809cbf86973b4735d0fb874ebbe392b mbs1/x86_64/mediawiki-sqlite-1.23.9-1.mbs1.noarch.rpm 0b17278c7df09036f5767b88fbc82be7 mbs1/SRPMS/mediawiki-1.23.9-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
