This seems to say that this issue won't be addressed in RHEL6 or RHEL7 however the released errata states that it was resolved.

https://rhn.redhat.com/errata/RHSA-2015-0066.html

Which is correct?

RHSA-2015:0066 updates openssl packages.  Quoted statement is for openssl097a and openssl098e compatibility packages.

Oh, of course. I understand now. Thanks.
