KDE Security Advisory: Two flaws in the Konqueror webbrowser make it possible to by pass the sandbox environment which is used to run Java-applets. One flaw allows access to restricted Java classes via JavaScript, making it possible to escalate the privileges of the Java-applet. The other problem is that Konqueror fails to correctly restrict access to certain Java classes from the Java-applet itself. All versions of KDE up to KDE 3.3.1 inclusive. KDE 3.3.2 is not affected.
