It looks like Ubuntu (and Debian by extension) patched it as well, I ran the test before and after an apt-get upgrade and got this output:

ronald at paragon:~$  env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
vulnerable
this is a test
ronald at paragon:~$  env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
this is a test


Pleasantly,
Ronald Bynoe

Damo,

   Slackware's dev team released a patched version yesterday evening. I'm
upgrading all systems here.
