Descriptions

The XML libraries for Python 3.4, 3.3, 3.2, 3.1, 2.7, and 2.6, as used in OpenStack Keystone Essex and Folsom, Django, and possibly other products allow remote attackers to read arbitrary files via an XML external entity declaration in conjunction with an entity reference, aka an XML External Entity (XXE) attack.

OpenStack Keystone Essex y Folsom permite a atacantes remotos leer ficheros arbitrarios a través de la declaración de una entidad externa XML junto con una referencia entidad, también conocido como un ataque XML External Entity (XXE).

The openstack-cinder packages provide OpenStack Volume, which provides services to manage and access block storage volumes for use by virtual machine instances. A denial of service flaw was found in the Extensible Markup Language parser used by Cinder. A remote attacker could use this flaw to send a specially-crafted request to a Cinder API, causing Cinder to consume an excessive amount of CPU and memory. A flaw was found in the XML parser used by Cinder. If a remote attacker sent a specially-crafted request to a Cinder API, it could cause Cinder to connect to external entities, causing a large amount of system load, or allow an attacker to read files on the Cinder server that are accessible to the user running Cinder.
