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 Pat Riehecky 2015-10-23 18:48:35 UTC 
Verified on default EL6

+++ This bug was initially created as a clone of Bug #1274876 +++

Description of problem:
The default configuration of mod_ssl in EL5 permits SSLv3 connections.  Per CVE-2014-3566 this protocol is known to be a security risk.

Version-Release number of selected component (if applicable):mod_ssl-2.2.3-87


How reproducible:100%


Steps to Reproduce:
1.Install apache with mod_ssl
2.enable connections to port 443 via apache mod_ssl using the default config
3.test a SSLv3 connection

Actual results:
SSLv3 connections are permitted

Expected results:
Since SSLv3 has known security issues, I expected it to be disabled by default.
