Debian Security Advisory 3046-1
Posted Oct 6, 2014
Authored by Debian | Site debian.org

Debian Linux Security Advisory 3046-1 - 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.

Package : mediawiki
CVE ID : CVE-2014-7295

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.
