Vulnerability CVE-2013-4185

Vulnerability Name:

CVE-2013-4185 (CCN-86297)

Assigned:

2013-08-06

Published:

2013-08-06

Updated:

2018-11-15

Summary:

Algorithmic complexity vulnerability in OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-3 does not properly handle network source security group policy updates, which allows remote authenticated users to cause a denial of service (nova-network consumption) via a large number of server-creation operations, which triggers a large number of update requests.
