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.

Bug 1119800

Summary: ECC supported curves list extension is missing in DTLS1 client hello

Fixed In Version: openssl-1.0.1e-30.el6 Doc Type: Bug Fix
Doc Text:
The TLS extensions that were sent in the Datagram TLS (DTLS) ClientHello requests did previously not contain the list of the supported elliptic curves. As a consequence, the DTLS connections to servers using elliptic curves not supported by the OpenSSL client were aborted. With this update, the elliptic curve list extension is properly sent in the DTLS ClientHello requests, and DTLS connections are no longer aborted in the above circumstances.

Description Tomas Mraz 2014-07-15 14:37:41 UTC 
ECC supported curves list extension is missing in DTLS1 client hello message. Because we do not support all of the ECC curves that are currently widely used this severally worsens the interoperability of DTLS1 protocol in our openssl package.

Upstream recently fixed this issue.
