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 of problem:
Starting from upstream version 0.1.44 SCAP Security Guide produces SCAP 1.3 conformant datastreams, which includes RHSA OVAL feed as a datastream component.
This remote component is used in rule `security_patches_up_to_date`,
OpenSCAP fails to load SCAP 1.3 datastreams with remote components unless `--fetch-remote-resources` is provided. That means to be able to use these datastreams, a remote content must be download from the internet by `oscap`. This isn't acceptable for users who have no internet connection.
Version-Release number of selected component (if applicable):
openscap-1.2.17
How reproducible:
always
Steps to Reproduce:
1. get SCAP 1.3 datastream with a remote component, eg. from upstream SSG
2. run oscap scan
3.
Actual results:
`oscap` fails to load the datastream if `--fetch-remote-resources` is not provided
----8<----8<----8<----8<----8<----8<----
WARNING: Datastream component 'scap_org.open-scap_cref_security-data-oval-com.redhat.rhsa-RHEL7.xml.bz2' points out to the remote 'https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL7.xml.bz2'. Use '--fetch-remote-resources' option to download it.
WARNING: Skipping 'https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL7.xml.bz2' file which is referenced from datastream
OpenSCAP Error: Could not extract scap_org.open-scap_cref_ssg-rhel7-xccdf-1.2.xml with all dependencies from datastream. [/builddir/build/BUILD/openscap-1.3.0/src/DS/ds_sds_session.c:210]
----8<----8<----8<----8<----8<----8<----
Expected results:
`oscap` doesn't require to download anything from the internet to process SCAP 1.3 datastream, remote component is skipped, rule security_patches_up_to_date isn't evaluated, but all other rules are evaluated.
Additional info:
Fixed upstream in https://github.com/OpenSCAP/openscap/pull/1324
