Description Jan Lieskovsky 2012-04-11 15:08:11 UTC
A potential out-of stack-based buffer bounds write flaw was reported:
[1] http://sourceforge.net/mailarchive/message.php?msg_id=29011989

in the way Flight Gear, the flight simulator, retrieved rotor name for certain rotor models. A remote attacker could provide a specially-crafted rotor model XML data file, which once opened by a local, unsuspecting user in FlightGear would lead to 'fgfs' executable crash.

CVE Request:
[2] http://www.openwall.com/lists/oss-security/2012/04/10/9

CVE Assignment:
[3] http://www.openwall.com/lists/oss-security/2012/04/10/13

Upstream patch:
None as of right now.

Note:
Report [1] mentions possibility of stack buffer overflow also in SimGear's:
simgear/simgear/simgear/io/sg_socket_udp.cxx:

line 101     int SGSocketUDP::read( char *buf, int length ) {
                .
                .
                .
line 108     if ( (result = sock.recv(buf, SG_IO_MAX_MSG_SIZE, 0)) >= 0 ) {

routine. Though I am not sure, how that one could be exploited remotely by the attacker, thus didn't include that use case here.
