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:

Cups can't disable SSLv3, so stunnel is the only workarround, per https://access.redhat.com/site/solutions/1234843

Please backport, the Upstream Fix: http://www.cups.org/str.php?L4476

cups-str4476.patch (RHEL-7)

Here's the patch I plan to use.

It's a more or less straightforward back-port.

It augments the cupsd.conf "SSLOptions" keyword to include two new options, AllowRC4 and AllowSSL3, each of which enables the named feature in cupsd. The default is now to disable both RC4 and SSL3 for cupsd.

It also introduces the new /etc/cups/client.conf "SSLOptions" keyword, with options AllowRC4 and AllowSSL3. In order to enforce this correctly, the system-wide /etc/cups/client.conf file is read first, and the user ~/.cups/client.conf file (in which "SSLOptions" is not valid) is read afterwards. The default is now for clients to use neither RC4 nor SSL3.
