Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

This is generally non-critical (as well as for ricci side: [bug 1156157])
but taking recent affairs into account, would deserve at least a dedicated
tracking -- properties of secure channel towards ricci hasn't been on the
table yet.

Principially, [bug 1156167] is of greater concerns, though.


+++ This bug was initially created as a clone of Bug #1156167 +++

Due to an ever-increasing attention being paid to minimal acceptable
version of SSL/TLS and/or their ciphers (security scanners, etc.)
and because luci[-ricci] communication should be just fine with TLS1.0+.

[...]

To be noted that relying merely on security scanners tends to provide
false sense of overall security; certificate management (conga, as in
ricci+luci, using self-signed ones with limited options to roll up custom
ones) is perhaps comparably weak point here (see also [bz885028]).
