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 2017-06-27 23:53:22 UTC 
Description of problem:
Multiple rules shipped in SSG have either missing remediations, or remediations that fails when applied on freshly installed system. These rules are (to help with development, it's grouped by example of profile where these are enabled):

(STIG profile)
xccdf_org.ssgproject.content_rule_ntp_set_maxpoll (missing)
xccdf_org.ssgproject.content_rule_sssd_enable_pam_services (missing)
xccdf_org.ssgproject.content_rule_rsyslog_remote_loghost (failing)
xccdf_org.ssgproject.content_rule_accounts_passwords_pam_faillock_deny_root (failing)
xccdf_org.ssgproject.content_rule_grub2_enable_fips_mode (failing)

(PCI-DSS profile)
xccdf_org.ssgproject.content_rule_ensure_logrotate_activated (missing)

(OSPP profile)
xccdf_org.ssgproject.content_rule_network_ipv6_privacy_extensions (missing)
xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_all_forwarding (missing)
xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_default_accept_source_route (missing)
xccdf_org.ssgproject.content_rule_network_ipv6_disable_rpc (missing)
xccdf_org.ssgproject.content_rule_sysctl_kernel_ipv6_disable (missing)
xccdf_org.ssgproject.content_rule_aide_scan_notification (failing)

(C2S profile)
xccdf_org.ssgproject.content_rule_sshd_set_loglevel_info (missing)
xccdf_org.ssgproject.content_rule_mount_option_dev_shm_noexec (missing)
xccdf_org.ssgproject.content_rule_mount_option_nodev_nonroot_local_partitions (missing)


Version-Release number of selected component (if applicable):
scap-security-guide-0.1.33-5.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. install fresh RHEL7.4 machine
2. perform profile based remediations for aforementioned profiles



Actual results:
2. rules listed  in description are still failing after remediation

Expected results:
2. rules listed in description are passing after remediation

Comment 2 Watson Yuuma Sato 2017-11-16 14:04:46 UTC 
Some more fixes:

For Rule xccdf_org.ssgproject.content_rule_ntp_set_maxpoll, which I believe actually is xccdf_org.ssgproject.content_rule_chronyd_or_ntpd_set_maxpoll:
https://github.com/OpenSCAP/scap-security-guide/pull/2429
https://github.com/OpenSCAP/scap-security-guide/pull/2432

For Rule xccdf_org.ssgproject.content_rule_rsyslog_remote_loghost (failing):

Comment 3 Watson Yuuma Sato 2018-07-18 13:12:53 UTC 
These rules were fixed in https://bugzilla.redhat.com/show_bug.cgi?id=1570802

(STIG profile)
xccdf_org.ssgproject.content_rule_sssd_enable_pam_services (missing)

(PCI-DSS profile)

xccdf_org.ssgproject.content_rule_aide_scan_notification (failing) was fixed in https://bugzilla.redhat.com/show_bug.cgi?id=1540505


Rules for which I did not patches, so I assume they still are failing or missing fixes:

(C2S profile)
xccdf_org.ssgproject.content_rule_sshd_set_loglevel_info (missing)
xccdf_org.ssgproject.content_rule_mount_option_dev_shm_noexec (missing)
xccdf_org.ssgproject.content_rule_mount_option_nodev_nonroot_local_partitions (missing)

xccdf_org.ssgproject.content_rule_accounts_passwords_pam_faillock_deny_root (failing)
xccdf_org.ssgproject.content_rule_grub2_enable_fips_mode (failing)

xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_all_forwarding (missing)
xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_default_accept_source_route (missing)
Comment 4 Watson Yuuma Sato 2018-11-26 16:01:48 UTC 
In RHEL7.6,

the following rules is still failing:
xccdf_org.ssgproject.content_rule_sshd_set_loglevel_info (fail)

This rule returns error:
xccdf_org.ssgproject.content_rule_mount_option_dev_shm_noexec (error)
"The mount point '/dev/shm' is not even in /etc/fstab, so we can't set up mount options
Not remediating, because there is no record of /dev/shm in /etc/fstab"

The following rules are passing:
xccdf_org.ssgproject.content_rule_accounts_passwords_pam_faillock_deny_root
xccdf_org.ssgproject.content_rule_grub2_enable_fips_mode

xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_all_forwarding
xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_default_accept_source_route

This rule was removed:
xccdf_org.ssgproject.content_rule_mount_option_nodev_nonroot_local_partitions 

And this rules started to fail/error:

C2S profile
xccdf_org.ssgproject.content_rule_sshd_set_max_auth_tries (fail)
xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_all_disable_ipv6 (error)
xccdf_org.ssgproject.content_rule_audit_rules_kernel_module_loading (error)
xccdf_org.ssgproject.content_rule_audit_rules_login_events (error)

OSPP profile
xccdf_org.ssgproject.content_rule_package_dracut-fips_installed (fail)
xccdf_org.ssgproject.content_rule_file_permissions_sshd_pub_key (error)
xccdf_org.ssgproject.content_rule_file_permissions_sshd_private_key (error)
xccdf_org.ssgproject.content_rule_audit_rules_privileged_commands (error)
Comment 6 Watson Yuuma Sato 2019-05-07 11:59:21 UTC 
Changes to RHEL 7.7

This rule reports error, but then passes, in subsequent scan:
xccdf_org.ssgproject.content_rule_sysctl_net_ipv6_conf_all_disable_ipv6 (error)

Following rule are passing now:
xccdf_org.ssgproject.content_rule_audit_rules_privileged_commands (fixed in C2S profile) 
xccdf_org.ssgproject.content_rule_audit_rules_kernel_module_loading (fixed)
xccdf_org.ssgproject.content_rule_file_permissions_sshd_pub_key (fixed)
xccdf_org.ssgproject.content_rule_file_permissions_sshd_private_key (fixed)


xccdf_org.ssgproject.content_rule_audit_rules_privileged_commands (fails in OSPP profile, due to installation of screen package)
(audit_rules_privileged_commands is remedied, screen is installed, and becuase screen is a privileged command, final result of rule audit_rules_privileged_commands is fail)

Other rules not mentioned here are still failing.
