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.
Basically the same request is in the bug #1373836 (for RHEL6.9 now). We are aware of this issue and we plan to proceed with removing insecure algorithms in future releases.
While we're at it - can we also remove the arcfour ciphers?
My security scanner (Greenbone) reports:
> Vulnerability Insight
> The ‘arcfour‘ cipher is the Arcfour stream cipher with 128-bit keys. The Arcfour cipher is believed to be
> compatible with the RC4 cipher {[}SCHNEIER{]}. Arcfour (and RC4) has problems with weak keys, and
> should not be used anymore.
Currently this is not yet reflected on the customer portal:

But I don't know where I would let them know... So I came here ;)
