Vulnerability CVE-2013-1838


Published: 2013-03-22   Modified: 2013-03-23

Description:
OpenStack 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.
