Comment 4 Tomas Hoger 2015-03-17 08:59:24 UTC 
Elliptic Curve (EC) cryptography support was first enabled in Red Hat Enterprise Linux when openssl packages were updated from 1.0.0 to 1.0.1e in Red Hat Enterprise Linux 6.5.  The openssl 1.0.0 packages in Red Hat Enterprise Linux 6 before 6.5 were not affected by this issue.  Also openssl 0.9.x packages in Red Hat Enterprise Linux 5 and earlier were not affected.
