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
