Synopsis
========

KStars is vulnerable to a buffer overflow that could lead to arbitrary
code execution with elevated privileges.

Background
==========

KDE is a feature-rich graphical desktop environment for Linux and
Unix-like Operating Systems. KStars is a desktop planetarium for KDE.
It includes support for the Instrument Neutral Distributed Interface
(INDI).

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

    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  kde-base/kdeedu     < 3.3.2-r1                        >= 3.3.2-r1

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

Erik Sjolund discovered a buffer overflow in fliccd which is part of
the INDI support in KStars.

Impact
======

An attacker could exploit this vulnerability to execute code with
elevated privileges. If fliccd does not run as daemon remote
exploitation of this vulnerability is not possible. KDE as shipped by
Gentoo does not start the daemon in the default installation.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All KStars users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=kde-base/kdeedu-3.3.2-r1"
