[MediaWiki-announce] MediaWiki 1.3.11 released [SECURITY]

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 MediaWiki 1.3.11 is a security release. == Important security updates == A security audit found and fixed a number of problems. Users of MediaWiki 1.3.10 and earlier should upgrade to 1.3.11; users of 1.4 beta releases should upgrade to 1.4rc1. === Cross-site scripting vulnerability === XSS injection points can be used to hijack session and authentication cookies as well as more serious attacks. * Media: links output raw text into an attribute value, potentially ~ abusable for JavaScript injection. This has been corrected. * Additional checks added to file upload to protect against MSIE and ~ Safari MIME-type autodetection bugs. As of 1.3.10/1.4beta6, per-user customized CSS and JavaScript is disabled by default as a general precaution. Sites which want this ability may set $wgAllowUserCss and $wgAllowUserJs in LocalSettings.php. === Cross-site request forgery === An attacker could use JavaScript-submitted forms to perform various restricted actions by tricking an authenticated user into visiting a malicious web page. A fix for page editing in 1.3.10/1.4beta6 has been expanded in this release to other forms and functions. Authors of bot tools may need to update their code to include the additional fields. === Directory traversal === An unchecked parameter in image deletion could allow an authenticated administrator to delete arbitary files in directories writable by the web server, and confirm existence of files not deletable.
