DESCRIPTION:
A vulnerability has been reported in OpenStack Compute (Nova), which
can be exploited by malicious users to cause a DoS (Denial of
Service).

The vulnerability is caused due to the application not enforcing
quotas on the number of security group rules created. This can be
exploited to create multiple iptables rules and exhaust system
resources.

The vulnerability is reported in version 2012.1. Other versions may
also be affected.

SOLUTION:
Fixed in the GIT repository.
