Red Hat Security Advisory 2017-0025-01
Posted Jan 6, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-0025-01 - 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: 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. If SSL was enabled, a malicious user could use these open ports to gain access to unauthorized resources.
