For whatever reason Apple chose, the bash update is not applied via Software 
Update- you're seeing known behavior.  It's only getting updated if you apply 
the package from your link below.

Those of us who manage many macs are importing the package to our management 
tools and deploying it like any other package.

Subject: [lopsa-tech] Has anyone bothered to test vulnerability before & after 
updating bash?

On each machine that I update, I first run the "env=blahblah" test, see that 
it's vulnerable, and then update, and then repeat the test to confirm it's no 
longer vulnerable.

The patch on mac seems to not work.  All the other systems - linux - after 
updating are fine.  But vulnerability persists after applying all OSX updates.  
In Software Updates, I click "Update" and it says "Checking for updates..." and 
then "No updates available."  I confirm "Command Line Tools" was updated 
yesterday.  I've even rebooted since then.

The vulnerable version of bash on mac is 3.2.51, and patched is 3.2.53.  I 
confirmed after fully updating via Software Update and rebooting, I'm still at 
3.2.51.

After manually applying the update from  http://support.apple.com/kb/DL1769, 
the vulnerability goes away, and I'm at 3.2.53.

So far I've only observed this on one mac.  But I'm getting my hands on more 
systems to test more.
