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.

Fixed In Version:	openssl-1.1.1c-9.el8	Doc Type:	Known Issue
Doc Text:	.OpenSSL generates a malformed `status_request` extension in the `CertificateRequest` message in TLS 1.3 OpenSSL servers send a malformed `status_request` extension in the `CertificateRequest` message if support for the `status_request` extension and client certificate-based authentication are enabled. In such case, OpenSSL does not interoperate with implementations compliant with the `RFC 8446` protocol. As a result, clients that properly verify extensions in the `CertificateRequest` message abort connections with the OpenSSL server. To work around this problem, disable support for the TLS 1.3 protocol on either side of the connection or disable support for `status_request` on the OpenSSL server. This will prevent the server from sending malformed messages.	Story Points:	---

Description Alicja Kario 2019-09-04 19:31:12 UTC

Description of problem:
when OpenSSL is set up to support status_request extension and ask for client certificates, the CertificateRequest message will include a malformed status_request extension (a copy of the one sent in Certificate message).

I have not tried to reproduce it with RHEL version, but given information from above bugs, it does look like RHEL's version of OpenSSL is also affected.
