Nope
Where I work we run Redhat, CentOS and AIX for our UNIX servers. I'm responsible for the AIX portion and I've been testing a fix this morning. If you use openssl, and are running the affected versions, you are vulnerable no matter what flavor of OS you are running.
We’re a big RHEL shop here, but they use F5s for certificates along with VeriSign. Very little scuttlebutt this morning about it.
