Descriptions

OpenStack Object Storage (Swift) before 2.4.0 does not properly close client 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 2.4.0 no cierra correctamente las conexionen del cliente, 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 client-to-proxy connection. An OpenStack-authenticated attacker could remotely trigger this flaw to cause denial of service through excess memory consumption.
