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 vharyan 2023-03-15 17:38:41 UTC
Description of problem:
system account with uid >= 1000 is badly detected as user interactive account


Version-Release number of selected component (if applicable):
scap-security-guide-0.1.66-2.el8_7.noarch


Actual results:

in RHEL8's one, the check for "interactive users" relies only on DEFAULT_UID_MIN which is hardcoded to 1000.

But with Upstream code , it relies on both DEFAULT_UID_MIN but also shell being /sbin/nologin, additionally DEFAULT_UID_MIN is computed from the system's settings.


Expected results:

Openscap scan should consider DEFAULT_UID_MIN aswell as /sbin/nologin

Comment 1 Renaud Métrich 2023-03-16 07:50:46 UTC
This is an issue for customers having service accounts with UID >= 1000.

Would it be possible to rebase RHEL8's scap-security-guide against Upstream one?
Or at least backport the create_interactive_users_list_object() macro (see shared/macros/10-oval.jinja)?
