NVD Description

Note: Versions mentioned in the description apply only to the upstream mediawiki package and not the mediawiki package as distributed by Ubuntu.

MediaWiki before 1.19.6 and 1.20.x before 1.20.5 allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by a CDATA section containing valid UTF-7 encoded sequences in a SVG file, which is then incorrectly interpreted as UTF-8 by Chrome and Firefox.
