Detailsinfo

A vulnerability was found in SimGear 1.9.1/2.0.0/2.6.0 and classified as very critical. This issue affects the function Rotor::getValueforFGSet. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed 06/16/2012 as Bug 811617 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com.
