GLSA 201603-12: FlightGear, SimGear: Multiple vulnerabilities

Title:FlightGear, SimGear: Multiple vulnerabilities
Bugs: #426502, #468106


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


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.

Affected packages

Package Vulnerable Unaffected Architecture(s)
games-simulation/flightgear < 3.4.0 >= 3.4.0 All supported architectures
games-simulation/simgear < 3.4.0 >= 3.4.0 All supported architectures


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.


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


There is no known workaround at this time.


All Flightgear users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose

All Simgear users should upgrade to the latest version:

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