Upgrade yui to version 3.10.3 or higher.

Overview

yui is an open source JavaScript and CSS framework for building richly interactive web applications.

Affected versions of the package are vulnerable to Cross-site Scripting (XSS) via the io.swf file that was inadvertently reintroduced in version 3.10.2. A carefully constructed URL accessing io.swf directly could cause it to execute JavaScript and potentially expose cookies or other sensitive information from the hosted site.

This vulnerability is similar to CVE-2013-4941.
