Synopsis
========

The Java sandbox environment in Konqueror can be bypassed to access
arbitrary packages, allowing untrusted Java applets to perform
unrestricted actions on the host system.

Background
==========

KDE is a feature-rich graphical desktop environment for Linux and
Unix-like Operating Systems. Konqueror is the KDE web browser and file
manager.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  kde-base/kdelibs       < 3.3.2                           >= 3.3.2

Description
===========

Konqueror contains two errors that allow JavaScript scripts and Java
applets to have access to restricted Java classes.

Impact
======

A remote attacker could embed a malicious Java applet in a web page and
entice a victim to view it. This applet can then bypass security
restrictions and execute any command, or access any file with the
rights of the user running Konqueror.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All kdelibs users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose kde-base/kdelibs

Note: There is currently no fixed stable version for sparc.
