Disable SSLv3 support for Apache

In case you haven’t disabled support for SSLv3 for Apache yet – do so now! You can easily disable SSLv3 using your Apache configuration httpd.conf using the option -SSLv3:

SSLHonorCipherOrder on
SSLProtocol -ALL -SSLv3 +TLSv1 +TLSv1.1 +TLSv1.2
SSLCipherSuite ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS

As always, make sure to restart Apache afterwards. Note that depending on your setup you might need to set the list of supported protocols for each vhost entry separately.
