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 Marek Haicman 2016-12-13 16:31:51 UTC 
Description of problem:
Rule xccdf_org.ssgproject.content_rule_mount_option_var_tmp_bind tries to check whether mount is binded or not by searching /etc/mtab for bind option.

For some time now, /etc/mtab reflects kernel view - that there is no difference between binded and not binded - thus bind is not mentioned there. 

Version-Release number of selected component (if applicable):
scap-security-guide-0.1.30-3.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. 
2.
3.

Actual results:
rule check contents of /etc/mtab

Expected results:
rule utilize different approach (comparison of inodes?)

Note: Important part is binded.pass.sh scenario in this case - error is due to discrepancy between how scan and remediation are performed. See Bug 1463829
