This is the standard command:

  $ openssl version

  > OpenSSL 1.0.1f 6 Jan 2014

@stormbrew is correct about ubuntu, use -a or -v -b

    openssl version -v -b

I'm totally confused by this. I'm running ubuntu LTS 12.04 and did

    sudo aptitude update
    sudo aptitude upgrade openssl

and then ran

    openssl version -a

and got the same results as you. How can it be built on January 8th if the patch was just made today?

[EDIT] running

    sudo aptitude upgrade

upgraded properly and now I'm getting a version that was compiled earlier today. I'm guessing I needed to update another package as well. Probably `libssl`?

upgrade will work because it updates libssl1.0.0 which is the package you want upgraded :) Openssl is the command line package and libssl1.0.0 is the library. i was able to upgrade openssl without upgrading libssl1.0.0.

i wonder how many people will do apt-get update openssl and assume they have fixed it

Thank you. That makes more sense now.

I'm guessing that tons of people will run into this. I bet a blog post would get you some traffic... :)

The package is called libssl1.0.0 -- it holds the shared libraries, while the openssl package contains utilities.

As far as I can tell, on ubuntu this reports "OpenSSL 1.0.1 14 Mar 2012" for all ubuntu versions, including the fixed one.

With "openssl version -a" you can see the built time.

  root@x ~ # openssl version -a
  OpenSSL 1.0.1 14 Mar 2012
  built on: Mon Apr  7 20:33:29 UTC 2014

Same here.

I got a "security warning" update when I logged in to the server (good), ran apt-get and installed, did openssl version, got the string as noted above (which seemed just a tad out of date).

So... I built and installed from source, and got... the same string.

Annoying.

My Linux Mint machine (based on 13.10) went from 1.0.1e Feb 2014 to 1.01 Mar 2012 int the last 2 hours, so that's definitely new.

I think someone screwed up on the version string big time.

try: dpkg -s openssl
