Red Hat Security Advisory 2014-1119-01 - OpenStack Networking is a pluggable, scalable, and API-driven system that provisions networking services to virtual machines. Its main function is to manage connectivity to and from virtual machines. As of Red Hat Enterprise Linux OpenStack Platform 4.0, 'neutron' replaces 'quantum' as the core component of OpenStack Networking. A denial of service flaw was found in neutron's handling of allowed address pairs. As there was no enforced quota on the amount of allowed address pairs, a sufficiently authorized user could possibly create a large number of firewall rules, impacting performance or potentially rendering a compute node unusable.

A remote authenticated attacker could exploit this to cause a denial of service. Zhi Kun Liu discovered that OpenStack Neutron incorrectly filtered certain tokens. An attacker could possibly use this issue to obtain authentication tokens used in REST requests. Various other issues were also addressed.

Its main function is to manage connectivity to and from virtual machines. A denial of service flaw was found in Neutron's handling of allowed address pairs. There was no enforced quota on the amount of allowed address pairs, possibly allowing a sufficiently authorized user to create such a large number of firewall rules as to impact performance, or potentially render a compute node unusable.
