  script_tag(name:"insight", value:"USN 1466-1 fixed a vulnerability in Nova. The upstream patch introduced
a regression when a security group granted full access and therefore the
network protocol was left unset, causing an error in processing. This
update fixes the issue.

We apologize for the inconvenience.

Original advisory details:

 It was discovered that, when defining security groups in Nova using
 the EC2 or OS APIs, specifying the network protocol (e.g. 'TCP') in
 the incorrect case would cause the security group to not be applied
 correctly. An attacker could use this to bypass Nova security group
 restrictions.");
