2. Relevant releases/architectures:
Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch
OpenStack Networking (Neutron) 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.
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. (CVE-2014-3555)
Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Liping Mao from Cisco as the original reporter.
