Doc Type: If docs needed, set a value
Doc Text:
An access-control flaw was discovered in puppet-tripleo's IPtables rules management, which allowed the creation of TCP/UDP rules with empty port values. Some API services in Red Hat OpenStack Platform director are not exposed to public networks, which meant their $public_ssl_port value was set to empty (for example, openstack-glance, which is deployed by default on both undercloud and overcloud). If SSL was enabled, a malicious user could use these open ports to gain access to unauthorized resources.

Description Summer Long 2017-01-03 02:03:32 UTC 
Puppet IPtables rules management allows the creation of TCP / UDP rules with empty port value.Some API services in Director are not exposed to public networks,
which means $public_ssl_port are empty for some services (for example, 
Glance, which is deployed by default on both undercloud and overcloud).

If SSL is enabled, several IPtables rules are created without a
port specified, which opens all traffic for TCP protocol. Example
of rule:
-A INPUT -p tcp -m comment --comment "100 glance_registry_haproxy_ssl"
-m state --state NEW -j ACCEPT
