The remote OracleVM system is missing necessary patches to address critical security updates :
To disable SSLv2 client connections create the file /etc/sysconfig/openssl-ssl-client-kill-sslv2 (John Haxby) [orabug 21673934]
Backport openssl 08-Jan-2015 security fixes (John Haxby) [orabug 20409893]
fix CVE-2014-3570 - Bignum squaring may produce incorrect results
fix CVE-2014-3571 - DTLS segmentation fault in dtls1_get_record
fix CVE-2014-3572 - ECDHE silently downgrades to ECDH [Client]
fix CVE-2016-0797 - heap corruption in BN_hex2bn and BN_dec2bn
fix CVE-2015-3197 - SSLv2 ciphersuite enforcement
disable SSLv2 in the generic TLS method (can be reenabled by setting environment variable OPENSSL_ENABLE_SSL2)
fix CVE-2015-3195 - X509_ATTRIBUTE memory leak
