3. Description:
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).
