It was reported that MediaWiki, a website engine for collaborative work, allowed to load user-created CSS on pages where user-created JavaScript is not allowed. A wiki user could be tricked into performing actions by manipulating the interface from CSS, or JavaScript code being executed from CSS, on security-wise sensitive pages like Special:Preferences and Special:UserLogin. This update removes the separation of CSS and JavaScript module allowance. For the stable distribution (wheezy), this problem has been fixed in version 1:1.19.20+dfsg-0+deb7u1. For the unstable distribution (sid), this problem has been fixed in version 1:1.19.20+dfsg-1. We recommend that you upgrade your mediawiki packages.
