CVE-2013-1068 [MEDIUM] OpenStack Nova vulnerabilities
Title: OpenStack Nova vulnerabilities
Summary: Several security issues were fixed in OpenStack Nova.
Darragh O'Reilly discovered that the Ubuntu packaging for OpenStack Nova
did not properly set up its sudo configuration. If a different flaw was
found in OpenStack Nova, this vulnerability could be used to escalate
privileges. This issue only affected Ubuntu 13.10 and Ubuntu 14.04 LTS.

Bernhard M. Wiedemann and Pedraig Brady discovered that OpenStack Nova did
not properly verify the virtual size of a QCOW2 images. A remote
authenticated attacker could exploit this to create a denial of service via

CVE-2013-6491 OpenStack Quantum vulnerability
Title: OpenStack Quantum vulnerability
Summary: OpenStack Quantum could be made to expose sensitive information over the
network.
USN-2208-1 fixed vulnerabilities in OpenStack Cinder. This update provides
the corresponding updates for OpenStack Quantum.
Original advisory details:
JuanFra Rodriguez Cardoso discovered that OpenStack Cinder did not enforce
SSL connections when Nova was configured to use QPid and qpid_protocol is
set to 'ssl'. If a remote attacker were able to perform a machine-in-the-middle
attack, this flaw could be exploited to view sensitive information. Ubuntu
does not use QPid with Nova by default.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2013-6491 [MEDIUM] CVE-2013-6491 Openstack nova: qpid SSL configuration
CVE-2013-6491 Openstack nova: qpid SSL configuration
JuanFra Rodriguez Cardoso discovered that nova was not correctly enabling SSL parameters when using the qpid client. Enabling "qpid_protocol = ssl" in nova.conf would not result in SSL being used to commnicate to qpid. If qpid was not configured to enforce SSL this could lead to sensitive information being sent in the clear.
Discussion:
I don't think the qpid connection is actually successful, even with require_encryption off, so no data actually flows. Did you do any network tracing to confirm that data goes over the wire unencrypted?
---
Yes I did. It made the connection and worked as normal (with no ssl) even though
ssl was enabled in the nova.conf.
After applying the patch and restarting nova-compute it fails to connect to qpid

CVE-2013-6491: Setting Qpid SSL protocol sets wrong variable [openstack-3]
Description of problem:
Cloned from upstream bug https://bugs.launchpad.net/oslo/+bug/1158807
By default, TCP is used as transport for QPID connections. If you like to enable SSL, there is a flat 'qpid_protocol = ssl' available in nova.conf. However, python-qpid client is awaiting transport type instead of protocol. It seems to be a bug:
Solution: (https://github.com/openstack/nova/blob/master/nova/openstack/common/rpc/impl_qpid.py#L323)
WRONG: self.connection.protocol = self.conf.qpid_protocol
CORRECT: self.connection.transport = self.conf.qpid_protocol

JuanFra.
