Description Pat Riehecky 2015-10-23 18:44:55 UTC

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.
