I have a CentOS 6.5 VPS server...
$ uname -a Linux mary 3.14.4-x86_64-linode40 #1 SMP Tue May 13 12:25:05 EDT 2014 \ x86_64 x86_64 x86_64 GNU/Linux
When the news about the Heartbleed vulnerability came out, I shut it down.
It was running Apache, MySQL, and a Ruby on Rails app. It did use OpenSSL.
I'm pretty sure it was running with vulnerable versions of OpenSSL for some time.
I booted it up again today and ran
yum -y update.
I now seem to have the patched version of OpenSSL...

I think I have two options...
Revoke and reissue my SSL certificate for the domain and keep using the machine.
Assume the machine is compromised and delete it, create a whole new VPS, install everything.
Rebuilding the entire system is a 1-2 day job.
Is it necessary or overkill?
