You can find an Unofficial Patch with Source Code from eEye Digital Security HERE.
As with every Unofficial Patch : USE IT AT YOUR OWN RISK !

Edit:
That is most of the time the case with Unofficial Patches. They have to be researched first. So when they are published ( and if they are good ) it takes a few days before they are "recommended".
But the patch is published on several security- and non-security related websites.

Btw. I forgot to tell you that my source is sans.org
