(RHSA-2017:0025) Important: puppet-tripleo security update

puppet-tripleo is a key component of the Red Hat OpenStack Platform director, which is a toolset for installing and managing a complete OpenStack environment.

Security Fix(es):

• 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. (CVE-2016-9599)

This issue was discovered by Ben Nemec (Red Hat).
