Description: A vulnerability was reported in KDE. A remote user can conduct cross-site scripting attacks.
The software does not properly filter HTML code from user-supplied input in the HTML 'title' tag before displaying the input. A
remote user can create HTML on a web site that contains a specially crafted title value. When the site is loaded by a target user,
arbitrary scripting code will be executed by the target user's browser. The code will originate from the target site and will run
in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication
cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take
actions on the site acting as the target user.
Jose Avila discovered this vulnerability.
