Synopsis

The KHTML component shipped with the KDE libraries is prone to a cross-site scripting (XSS) vulnerability.

2. Impact Information

Background

KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. KHTML is the HTML interpreter used in Konqueror and other parts of KDE.

Description

The KHTML code allows for the execution of JavaScript code located inside the "Title" HTML element, a related issue to the Safari error found by Jose Avila.

Impact

When viewing a HTML page that renders unsanitized attacker-supplied input in the page title, Konqueror and other parts of KDE will execute arbitrary JavaScript code contained in the page title, allowing for the theft of browser session data or cookies.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All KDElibs users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdelibs-3.5.5-r8"
