An attacker can bypass the sandboxing of Nasal scripts and arbitrarily write to any file path that the user has permission to modify at the operating-system level.

Multiple format string vulnerabilities in FlightGear 2.6 and earlier and SimGear 2.6 and earlier 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 to (1) fgfs/flightgear/src/Cockpit/panel.cxx or (2) fgfs/flightgear/src/Network/generic.cxx, or (3) a scene graph model to simgear/simgear/scene/model/SGText.cxx.

Multiple buffer overflows in FlightGear 2.6 and earlier and SimGear 2.6 and earlier allow user-assisted remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a (1) long string in a rotor tag of an aircraft xml model to the Rotor::getValueforFGSet function in src/FDM/YASim/Rotor.cpp or (2) a crafted UDP packet to the SGSocketUDP::read function in simgear/simgear/simgear/io/sg_socket_udp.cxx.
