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 of problem:
BIND 9.11 line would be soon stop receiving any updates from upstream. I think it would be good to update to the latest release released in that major version. Currently version 9.11.35 [1] is the latest, only security and critical bugs get included into this version line. We should update to the latest code before upstream stops any maintenance on this version.

Version-Release number of selected component (if applicable):
bind-9.11.26-6.el8

Additional info:

1. https://downloads.isc.org/isc/bind9/9.11.35/RELEASE-NOTES-bind-9.11.35.html

Since the CVE-2021-25219 is the only change in latest release, I would include this change in a planned rebase. It would include few issue fixes not included in bind-9.11.26 current version.

1. https://downloads.isc.org/isc/bind9/9.11.36/RELEASE-NOTES-bind-9.11.36.html

Including to additional upstream bugs, which should be fixed by the rebase. That excludes security bugs, which were upgraded by backported fixes. Backported patches would be removed, since fixes are already in the new original upstream archive.
