Descriptions

OpenStack Object Storage (Swift) before 2.3.1 (Kilo), 2.4.x, and 2.5.x before 2.5.1 (Liberty) do not properly close server connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

OpenStack Object Storage (Swift) en versiones anteriores a 2.3.1 (Kilo), 2.4.x y 2.5.x en versiones anteriores a 2.5.1 (Liberty) no cierra correctamente las conexiones de servidor, lo que permite a atacantes remotos causar una denegación de servicio (consumo de recursos del servidor proxy) a través de una serie de peticiones interrumpidas a una URL Large Object.

A memory-leak issue was found in OpenStack Object Storage (swift), in the proxy-to-server connection. An OpenStack-authenticated attacker could remotely trigger this flaw to cause denial of service through excess memory consumption.
