I think it does!  It talks about problems that ECC, especially ECDH
support, was not available in some Red Hat distributions, it talks about
patent problems, and also
about that the issue was resolved, and that software using OpenSSL needed
be recompiled after taking the update. I do not know exactly what will
solve your problem but
upgrading your Red Hat distribution seems to be a good place to start!
