Users of Ubuntu are advised to implement updates to address various vulnerabilities in OpenStack Neutron and safeguard against possible exploit attempts.
Several security issues were fixed in OpenStack Neutron.

Summary

Several security issues were fixed in OpenStack Neutron.

Software Description:

- neutron: OpenStack Virtual Network Service

Details:

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)
