Descriptions

The python-qpid client (common/rpc/impl_qpid.py) in OpenStack Oslo before 2013.2 does not enforce SSL connections when qpid_protocol is set to ssl, which allows remote attackers to obtain sensitive information by sniffing the network.

El cliente python-qpid (common/rpc/impl_qpid.py) en OpenStack Oslo anterior a 2013.2 no fuerza conexiones SSL cuando qpid_protocol se establece a ssl, lo cual permite a atacantes remotos obtener información sensible escuchando la red.

The openstack-nova packages provide OpenStack Compute, which provides services for provisioning, managing, and using virtual machine instances. It was discovered that enabling "qpid_protocol = ssl" in the nova.conf file did not result in nova using SSL to communicate to Qpid. If Qpid was not configured to enforce SSL this could lead to sensitive information being sent unencrypted over the communication channel. A flaw was found in the way OpenStack Compute controlled the size of disk images. An authenticated remote user could use malicious compressed qcow2 disk images to consume large amounts of disk space, potentially causing a denial of service on the OpenStack Compute nodes.
