OSSA-2014-019: Neutron L3-agent DoS through IPv6 subnet

Date:June 18, 2014
CVE:CVE-2014-4167

Affects

  • Neutron: TODO

Description

Thiago Martins from Hewlett Packard reported a vulnerability in Neutron L3-agent. By creating an IPv6 private subnet attached to a L3 router, an authenticated user may break the L3-agent, preventing further floating IPv4 addresses from being attached for the entire cloud. Note: removal of the faulty network can not be done using the API and must be cleaned at the database level. Only Neutron setups using IPv6 and L3-agent are affected.
