neutron vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS
- Ubuntu 13.10


Several security issues were fixed in OpenStack Neutron.

Software Description:
- neutron: OpenStack Virtual Network Service


Darragh O'Reilly discovered that the Ubuntu packaging for OpenStack Neutron
did not properly set up its sudo configuration. If a different flaw was
found in OpenStack Neutron, this vulnerability could be used to escalate
privileges. (CVE-2013-6433)

Stephen Ma and Christoph Thiel discovered that the openvswitch-agent in
OpenStack Neutron did not properly perform input validation when creating
security group rules when specifying --remote-ip-prefix. A remote
authenticated attacker could exploit this to prevent application of
additional rules. (CVE-2014-0187)

Thiago Martins discovered that OpenStack Neutron would inappropriately
apply SNAT rules to IPv6 subnets when using the L3-agent. A remote
authenticated attacker could exploit this to prevent floating IPv4
addresses from being attached throughout the cloud. (CVE-2014-4167)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  python-neutron                  1:2014.1-0ubuntu1.3

Ubuntu 13.10:
  python-neutron                  1:2013.2.3-0ubuntu1.5

In general, a standard system update will make all the necessary changes.

  CVE-2013-6433, CVE-2014-0187, CVE-2014-4167
