Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Fixed In Version: gnutls-3.7.6-19.el9_0 Doc Type: Enhancement
Doc Text:
.GnuTLS requires EMS with TLS 1.2 in FIPS mode To comply with the FIPS-140-3 standard, GnuTLS servers and clients by default require the Extended Master Secret (EMS) extension (RFC 7627) for all TLS 1.2 connections negotiated in FIPS mode. If your scenario requires preserving compatibility with older servers and clients that do not support EMS and you cannot use TLS 1.3, you can opt-out of the system-wide cryptographic policies by adding the `tls-session-hash` option with the `request` value to the `/etc/crypto-policies/local.d/gnutls-no-ems.config` configuration file: ---- [overrides] tls-session-hash = request ---- After you add the option to `/etc/crypto-policies/local.d/gnutls-no-ems.config`, make the changes effective by entering the `update-crypto-policies` command. WARNING: If you allow TLS 1.2 connections without EMS, your system no longer meets the FIPS-140-3 requirements.
