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 Matus Marhefka 2022-09-14 16:24:02 UTC 
+++ This bug was initially created as a clone of Bug #2126882 +++

Description of problem:
openscap prints error when evaluating oval:ssg-file_permissions_sshd_private_key:def:1 OVAL definition and openssh-server RPM is not installed on the filesystem (no ssh_keys in /etc/group).

Version-Release number of selected component (if applicable):
openscap-1.3.6-4.el9
scap-security-guide-0.1.63-5.el9.noarch


How reproducible:
always


Steps to Reproduce:
Create a minimal chroot filesystem:
# mkdir -p /chroot_dir/var/lib/rpm
# rpm --root /chroot_dir --initdb
# dnf -y --disablerepo=* --enablerepo=rhel --enablerepo=rhel-AppStream --installroot=/chroot_dir install redhat-release filesystem yum rpm bash coreutils util-linux

# oscap-chroot /chroot_dir oval eval --id oval:ssg-file_permissions_sshd_private_key:def:1 /usr/share/xml/scap/ssg/content/ssg-rhel9-ds.xml
E: oscap:     Failed to convert OVAL state to SEXP, id: oval:ssg-filter_ssh_key_owner_ssh_keys:ste:1.
Definition oval:ssg-file_permissions_sshd_private_key:def:1: true
Evaluation done.

In case openssh-server RPM is installed into the chroot directory the error does not occur as there is ssh_keys in /etc/group:
# grep ssh_keys /chroot_dir/etc/group
ssh_keys:x:996:


Actual results:
Error is printed by openscap when evaluating oval:ssg-file_permissions_sshd_private_key:def:1 OVAL definition and openssh-server RPM is not installed on the filesystem (no ssh_keys in /etc/group).


Expected results:
No error
