Quick fix
PYSEC-2013-44 — nova: upgrade to the fixed version with the command below.
pip install --upgrade 'nova>=12.0.0a0'Details
OpenStack Compute (Nova) Grizzly, Folsom (2012.2), and Essex (2012.1) does not properly implement a quota for fixed IPs, which allows remote authenticated users to cause a denial of service (resource exhaustion and failure to spawn new instances) via a large number of calls to the addFixedIp function.
