Description Vasyl Kaigorodov 2015-01-09 09:47:41 UTC 
The below vulnerability in Neutron was reported [1]:

By creating 8 routers and assigning each of them a non-provider ipv6 subnet, a malicious user may block router update processing for all tenants, potentially resulting in a Denial of Service. Only Neutron setups running with radvd 2.0+ are affected.

FYI the only place where we run with radvd 2.+ is Fedora Rawhide, and this will be fixed during the next rebase to latest Juno release.
