| Package | Affected versions | Patched versions |
|---|---|---|
| puppet-tripleo | = 5.5.0= 6.2.0 | |
| openstack | = 10 |
puppet-tripleo before versions 5.5.0, 6.2.0 is vulnerable to an access-control flaw in the IPtables rules management, which allowed the creation of TCP/UDP rules with empty port values. If SSL is enabled, a malicious user could use these open ports to gain access to unauthorized resources.
