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 2017-06-21 20:26:16 UTC 
Description of problem:
Rule xccdf_org.ssgproject.content_rule_mount_option_var_tmp_bind is currently defined in such way it cannot be remedied. OVAL checks runtime, and remediation deals solely with /etc/fstab.

Version-Release number of selected component (if applicable):
scap-security-guide-0.1.33-5.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. make two entries into /etc/fstab, separately for /tmp and /var/tmp
2. run remediation
3. check runtime and contents of /etc/fstab

Actual results:
fstab is updated to include binding mount of /tmp to /var/tmp. Runtime is still failing

Expected results:
Runtime is fixed together with fstab, by remounting

Comment 1 Watson Yuuma Sato 2018-07-31 16:15:07 UTC 
I believe this is addressed by this PR: https://github.com/OpenSCAP/scap-security-guide/pull/2696

The mount_option rules were templated and now the generated remediations (ansible and bash) can mount the partition.
