Descriptions

OpenStack Compute (Nova) Folsom, Grizzly, and earlier, when using Apache Qpid for the RPC backend, does not properly handle errors that occur during messaging, which allows remote attackers to cause a denial of service (connection pool consumption), as demonstrated using multiple requests that send long strings to an instance console and retrieving the console log.

En OpenStack Compute (Nova) Folsom, Grizzly, y anteriores, cuando se utiliza Apache Qpid para el backend RPC, no maneja adecuadamente los errores que se producen durante la mensajería, que permite a atacantes remotos provocar una denegación de servicio (conexión consumo piscina), como lo demuestra el uso de múltiples solicitudes que envían cadenas largas a una consola de instancia y recuperar el registro de la consola.
