Therefore, openssl packages in Red Hat Enterprise Linux 5 and earlier, which are based on upstream version 0.9.8 and earlier, are not affected by this issue. Additionally, the openssl packages shipped in Red Hat Enterprise Linux 6 prior to update RHBA-2013:1585 released as part of Red Hat Enterprise Linux 6.5 were also not affected, as Elliptic Curve Cryptography (ECC) support was not enabled.
