is there a patch against "Shell Shock" for my system MacOS 10.6.8 bash version 3.2.48(1)-release (x86_64-apple-darwin10.0)
Apple has quietly dropped support for Snow Leopard and earlier versions. This page has various means of helping you to compile your own version should you wish to do so:

How do I recompile Bash to avoid Shellshock (the remote exploit CVE-2014-6271 and CVE-2014-7169)?

There is a lot of attention on all the posts on that page. Read it all and find the solution that feels the most comfortable for you. Asking there is probably going to get you more eyeballs than asking here.
