heartbeat openssl fix fedora 16

I am in the process of patching two redhat servers. They are only used for mail no hosted websites, but we are using SSL for mail.

One of the servers is an older version of redhat (Redhat version 16)

Linux version 3.1.0-7.fc16.x86_64 (mockbuild@x86-07.phx2.fedoraproject.org)
(gcc version 4.6.2 20111027 (Red Hat 4.6.2-1) (GCC) )

If I do a yum update openssl it will return that it is pulling
1.0.0j-1.fc16 not the most current patched version

The current version on the server.
OpenSSL 1.0.0e-fips 6 Sep 2011

From what I have been reading openssl versions under the 1.0.0 branch are not affected.

With that said is there any way I can test this on the server. From what I am reading this vulnerability does not affect this server due to the version of openssl but I want to be sure.

The version you are on is not affected -

https://www.openssl.org/news/secadv_20140407.txt

TLS heartbeat read overrun (CVE-2014-0160)
==========================================

A missing bounds check in the handling of the TLS heartbeat extension can be
used to reveal up to 64k of memory to a connected client or server.

Only 1.0.1 and 1.0.2-beta releases of OpenSSL are affected including
1.0.1f and 1.0.2-beta1.

Yes, you can test online here: http://filippo.io/Heartbleed/

And here's a little program for testing: https://gist.github.com/sh1n0b1/10100394#file-ssltest-py

Happy patching ;)

Thanks guys. What is your opinion regarding fedora 16. Should I update to the latest version and can that be done through a yum update? This was setup by someone else a long time ago.

Which 'latest' version?

Update is fine, I recommend leave openssl alone until the bug is fixed, consider you are not unaffected.

"Which 'latest' version?"

Mazdajai I was noticing current versions of fedora are 19 and 20. All the openssl patch info seems related to those version.  I was a bit concerned we are falling far behind on the version of fedora, but as you said I think I'll just leave it alone for now.
