Descriptions

The (1) backup (api/contrib/backups.py) and (2) volume transfer (contrib/volume_transfer.py) APIs in OpenStack Cinder Grizzly 2013.1.3 and earlier allows remote attackers to cause a denial of service (resource consumption and crash) via an XML Entity Expansion (XEE) attack. NOTE: this issue is due to an incomplete fix for CVE-2013-1664.

El (1) backup (api/contrib/backups.py) y (2) el APIs de transferencia de almacenamiento (contrib/volume_transfer.py) en OpenStack Cinder Grizzly 2013.1.3 y anteriores permite a atacantes remotos provocar una denegación de servicio (consumo de recursos y caída) a través de un ataque XML Entity Expansion (XEE). NOTA: esta cuestión es debido a una solución incompleta del CVE-2013-1664.

The openstack-cinder packages provide OpenStack Volume, which provides services to manage and access block storage volumes for use by virtual machine instances. It was found that the fixes for CVE-2013-1664 and CVE-2013-1665, released via RHSA-2013:0658, did not fully correct the issues 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, or possibly crash.
