Correct way to find this (shellshock patch) package?

I was out to patch some squeeze servers for the shellshock bug. A few googles later I found that I could updated my apt sources list . This did however not work for some reason. I tried to search for the package at packages.debian.org without luck. It took me a good while to find this post , which was the solution to my problems. My question is, how can I find these packages directly, without finding a blog post about them? Am I just looking at the wrong place at packages.debian.org? I tried listing all squeeze and squeeze-updates packages, and I only found non-patched bash packages.
