Same here.
Meanwhile, better update your bash ASAP.
You can test for the vulnerability: in shell enter the command
env X="() { :;} ; echo busted" /bin/sh -c "echo stuff"
if you get "busted" back, you are vulnerable. If you get something like
/bin/sh: warning: X: ignoring function definition attempt
/bin/sh: error importing function definition for `X'
stuff
Then your'e fine.
