RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
The ip(6)tables service has a severe issue that impacts the ability to use configuration management automation solutions and is a security vulnerability opening up the firewall for host attack. When the firewall is in the stopped state, the execution of ip(6)tables -L restarts the firewall with a blank configuration.
Version-Release number of selected component (if applicable):
iptables-1.4.7-16.el6.x86_64
iptables-ipv6-1.4.7-16.el6.x86_64
How reproducible:
Always
Steps to Reproduce:
1. service ip(6)tables stop
2. service ip(6)tables status
(shows ip(6)tables: Firewall is not running)
3. iptables -L
4. service ip(6)tables status
Actual results:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Expected results:
Should show "ip(6)tables: Firewall is not running", and should not be in the running state.
Additional info:
The iptables -L command is loading netfilter modules if they are not loaded, yet.
The iptables init script is offering a way to list the rules only if the base netfilter modules are loaded: "service iptables status"
Also iptables-save can be used.
Closing this bug as not a bug.
