CVE-2017-8921 (opens in a new tab)How to fix?
Upgrade Debian:8 flightgear to version 3.0.0-5+deb8u2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream flightgear package and not the flightgear package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
In FlightGear before 2017.2.1, the FGCommand interface allows overwriting any file the user has write access to, but not with arbitrary data: only with the contents of a FlightGear flightplan (XML). A resource such as a malicious third-party aircraft could exploit this to damage files belonging to the user. Both this issue and CVE-2016-9956 are directory traversal vulnerabilities in Autopilot/route_mgr.cxx - this one exists because of an incomplete fix for CVE-2016-9956.
