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 Marek Haicman 2016-12-13 17:14:11 UTC 
Description of problem:
Remediation rule for rule_rsyslog_files_permissions alters /etc/rc.local. On RHEL7, this file is there for legacy reasons, provided by systemd, and is not configured to be altered, so any update is manifested in rpm -V systemd failing. 

Version-Release number of selected component (if applicable):
scap-security-guide-0.1.30-3.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. run remediation script of rule_rsyslog_files_permissions rule
2. rpm -Va


Actual results:
Failure as /etc/rc.local is altered.

Expected results:
Success - only files which are allowed to be changed are changed.

Comment 2 Marek Haicman 2017-03-09 15:50:51 UTC 
Description has few typos/maybe is not clear enough, so short [hopefully correct :)] description of the problem [original in "See Also" ticket is ok]:

Remediation of rule_rsyslog_files_permissions updates file /etc/rc.d/rc.local and changes also changes file permissions. Because of this change, rule rpm_verify_permissions starts failing.
Comment 3 Raphael Sanchez Prudencio 2017-03-14 09:58:51 UTC 
Proposed PR at https://github.com/OpenSCAP/scap-security-guide/pull/1756
Comment 5 Marek Haicman 2017-04-24 17:53:29 UTC 
If I am not mistaken, PR linked in this bug actually introduced regression. /var/log/boot.log needs special handling in RHEL7, as it retains 644 after reboot, the same way it does on RHEL6. Only the workaround [using rc.local file] is not available on RHEL7.

Moving back to assigned.
Comment 7 Raphael Sanchez Prudencio 2017-05-10 09:14:43 UTC 
Looks like Plymouth was changed in 7.4 so it won't truncate/touch /var/log/boot.log anymore, maybe this helps us getting rid of the workaround that was removed as accident.
Comment 8 Raphael Sanchez Prudencio 2017-05-15 13:28:56 UTC 
Ray Strode fixed the issue on plymouth-0.8.9-0.28.20140113.el7.x86_64, it was enforcing mode 0644. 

The remediation should be enough now and work properly.
