https://notcve.org/view.php?id=CVE-2012-2101

Openstack Compute (Nova) Folsom, 2012.1, and 2011.3 does not limit the number of security group rules, which allows remote authenticated users with certain permissions to cause a denial of service (CPU and hard drive consumption) via a network request that triggers a large number of iptables rules. Openstack Compute (Nova) Folsom v2012.1 y v2011.3 no limitan el número de reglas de seguridad del grupo, lo que permite causar una denegación de servicio (excesivo consumo de CPU y de disco duro) a usuarios remotos autenticados con determinados permisos a través de una solicitud de red que provoca una gran número de reglas de iptables. • http://lists.fedoraproject.org/pipermail/package-announce/2012-May/079434.html http://lists.fedoraproject.org/pipermail/package-announce/2012-May/079551.html http://secunia.com/advisories/49034 http://secunia.com/advisories/49048 http://ubuntu.com/usn/usn-1438-1 http://www.osvdb.org/81641 https://bugs.launchpad.net/nova/+bug/969545 https://exchange.xforce.ibmcloud.com/vulnerabilities/75243 https://github.com/openstack/nova/commit/1f644d210557b1254f7c7b39424b09a45329ade7 https://github.com/opens • CWE-264: Permissions, Privileges, and Access Controls •
