Description Jan Černý 2019-05-13 14:58:39 UTC
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

The fix is about discerning return output when remote content was not downloaded.
