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.

Doc Text:
*OpenSCAP* now handles also uncompressed XML files in a CVE OVAL feed Previously, the *OpenSCAP* tool was able to handle only compressed CVE OVAL files from a feed. As a consequence, the CVE OVAL feed provided by Red Hat cannot be used as a base for vulnerability scanning. With this update, *OpenSCAP* supports not only ZIP and BZIP2 files but also uncompressed XML files in a CVE OVAL feed, and the CVE OVAL-based scanning works properly without additional steps.

Description Przemek Klosowski 2017-04-07 14:17:16 UTC 
Description of problem:
xccdf scan using the common profile requires remote content from RedHat. When this is enabled by --fetch-remote-resources, an XML parse error appears and scan is aborted

Version-Release number of selected component (if applicable):
openscap-scanner-1.2.10-3.el7_3.x86_64

How reproducible: every time


Steps to Reproduce:
1. oscap xccdf eval --fetch-remote-resources --profile xccdf_org.ssgproject.content_profile_common --report /tmp/report-remote.html /usr/share/xml/scap/ssg/content/ssg-rhel7-ds.xml


Actual results:
Downloading: http://www.redhat.com/security/data/oval/Red_Hat_Enterprise_Linux_7.xml ... ok
OpenSCAP Error: Unable to parse XML from user memory buffer [oscap_source.c:254]
Failed to create OVAL definition model from: 'http://www.redhat.com/security/data/oval/Red_Hat_Enterprise_Linux_7.xml'. [xccdf_session.c:787]

Expected results: successful scan
Comment 2 Jan Černý 2017-04-18 13:56:33 UTC 
This was fixed in OpenSCAP 1.2.11 by this patch: https://github.com/OpenSCAP/openscap/commit/bc9db8a31a977d8f7a89ff3d98df939d9269007b

A workaround is to use compressed version of the remote XML file:
# sed -i "s@http://www.redhat.com/security/data/oval/Red_Hat_Enterprise_Linux_7.xml@https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL7.xml.bz2@" /usr/share/xml/scap/ssg/content/ssg-rhel7-ds.xml
Comment 7 Marek Haicman 2017-06-06 21:36:17 UTC 
Verified version openscap-1.2.14-2.el7.x86_64 fixes the issue

Please note, that the issue is also mitigated by use of newer SCAP Security Guide, for example scap-security-guide-0.1.33-5.el7.noarch (because it uses bz2 by default)
