Synopsis

Moderate: openstack-nova security and bug fix update

Type/Severity

Security Advisory: Moderate

Topic

Updated openstack-nova packages that fix two security issues and various
bugs are now available for Red Hat OpenStack Folsom.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

The openstack-nova packages provide OpenStack Compute (code name Nova),
which provides services for provisioning, managing, and using virtual
machine instances.

A flaw was found in the way the Nova VNC proxy handled console tokens. In
some cases, a console token that was valid for one virtual machine could
be used to connect to the console of a different user's virtual machine.
Note that this flaw did not bypass the normal user name and password
authentication on the virtual machine. The attacker would need to know
valid credentials to log into the virtual machine. (CVE-2013-0335)

There was no limit on the number of fixed IP addresses a virtual machine
could be assigned with. This could lead to a denial of service if an
attacker assigned all available IP addresses to their virtual machine. With
this update, a default limit of 10 IP addresses per virtual machine is
enforced. The "quota_fixed_ips" option in "/etc/nova/nova.conf" can be
used to set a higher or lower limit. (CVE-2013-1838)

Red Hat would like to thank the OpenStack project for reporting these
issues. Upstream acknowledges Loganathan Parthipan (HP) and Rohit Karajgi
(NTT Data) as the original, independent reporters of CVE-2013-0335, and
Vish Ishaya (Nebula) as the original reporter of CVE-2013-1838.

This update also fixes various bugs in the openstack-nova packages.

All users of openstack-nova are advised to upgrade to these updated
packages, which correct these issues. After installing the updated
packages, the running Nova services will be restarted automatically.
