Synopsis
========

Multiple vulnerabilities have been found in FlightGear and SimGear
allowing remote attackers to cause Denial of Service and possibly
execute arbitrary code.

Background
==========

FlightGear is an open-source flight simulator.  It supports a variety
of popular platforms (Windows, Mac, Linux, etc.) and is developed by
skilled volunteers from around the world.  Source code for the entire
project is available and licensed under the GNU General Public License.

SimGear is a set of open-source libraries designed to be used as
building blocks for quickly assembling 3d simulations, games, and
visualization applications.

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

Multiple format string vulnerabilities in FlightGear and SimGear allow
user-assisted remote attackers to cause a denial of service and
possibly execute arbitrary code via format string specifiers in certain
data chunk values in an aircraft xml model.

Impact
======

Remote attackers could possibly execute arbitrary code or cause Denial
of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Flightgear users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=games-simulation/flightgear-3.4.0"

All Simgear users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose
 ">=games-simulation/simgear-3.4.0"
