Summary: Openstack DBaaS (Trove) Improper Link Resolution Before File Access

Details: The `_write_config` function in `trove/guestagent/datastore/experimental/mongodb/service.py`, `reset_configuration` function in `trove/guestagent/datastore/experimental/postgresql/service/config.py`, `write_config` function in `trove/guestagent/datastore/experimental/redis/service.py`, `_write_mycnf` function in `trove/guestagent/datastore/mysql/service.py`, `InnoBackupEx::_run_prepare` function in `trove/guestagent/strategies/restore/mysql_impl.py`, `InnoBackupEx::cmd` function in `trove/guestagent/strategies/backup/mysql_impl.py`,`MySQLDump::cmd` in `trove/guestagent/strategies/backup/mysql_impl.py`, `InnoBackupExIncremental::cmd` function in `trove/guestagent/strategies/backup/mysql_impl.py`, `_get_actual_db_status` function in `trove/guestagent/datastore/experimental/cassandra/system.py` and `trove/guestagent/datastore/experimental/cassandra/service.py`, and multiple class CbBackup methods in `trove/guestagent/strategies/backup/experimental/couchbase_impl.py` in Openstack DBaaS (aka Trove) as packaged in Openstack before 2015.1.0 (aka Kilo) allows local users to write to configuration files via a symlink attack on a temporary file.
