Debian DSA-3046-1 : mediawiki - security update

low Nessus Plugin ID 78047

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the mediawiki packages.

For the stable distribution (wheezy), this problem has been fixed in version 1:1.19.20+dfsg-0+deb7u1.
