Ubuntu 14.04 LTS : OpenStack Nova vulnerabilities (USN-2247-1)

high Nessus Plugin ID 76109

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

Darragh O'Reilly discovered that 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. (CVE-2013-1068)

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 disk consumption. This issue did not affect Ubuntu 14.04 LTS. (CVE-2013-4463, CVE-2013-4469)

JuanFra Rodriguez Cardoso discovered that OpenStack Nova 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 man-in-the-middle attack, this flaw could be exploited to view sensitive information. Ubuntu does not use QPid with Nova by default. This issue did not affect Ubuntu 14.04 LTS. (CVE-2013-6491)

Loganathan Parthipan discovered that OpenStack Nova did not properly create expected files during KVM live block migration. A remote authenticated attacker could exploit this to obtain root disk snapshot contents via ephemeral storage. This issue did not affect Ubuntu 14.04 LTS. (CVE-2013-7130)

Stanislaw Pitucha discovered that OpenStack Nova did not enforce the image format when rescuing an instance. A remote authenticated attacker could exploit this to read host files. In the default installation, attackers would be isolated by the libvirt guest AppArmor profile. This issue only affected Ubuntu 13.10.
(CVE-2014-0134)

Mark Heckmann discovered that OpenStack Nova did not enforce RBAC policy when adding security group rules via the EC2 API. A remote authenticated user could exploit this to gain unintended access to this API. This issue only affected Ubuntu 13.10. (CVE-2014-0167).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
