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?
Comment 10 Tomas Hoger 2015-01-20 22:20:05 UTC
RHSA-2015:0066 updates openssl packages. Quoted statement is for openssl097a and openssl098e compatibility packages.
