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-1.0.2k-3.el7
Doc Type: Deprecated Functionality
Doc Text:
The SSL 2.0 support is completely removed from OpenSSL The SSL 2.0 protocol is severally broken and insecure, it was deprecated many years ago and it is not used anymore. Its support was already disabled by default. However to avoid inadvertent reenablement of the insecure protocol its support was removed completely. The OpenSSL library API calls that implement the protocol will permanently return error.

Red Hat Product Errata RHBA-2017:1929 0 normal SHIPPED_LIVE openssl bug fix and enhancement update 2017-08-01 18:08:01 UTC

Description Tomas Mraz 2016-03-23 09:31:27 UTC 
We should completely remove the support for SSL 2.0 except for receiving SSLv2 client hellos on the server.

The support will not be compiled into the library. To avoid ABI break the SSL2 specific public functions will be kept but they will return an error.
