You could check your system if it's vulnerable or not,from a command line, type:
Code: [Select]
env x='() { :;}; echo vulnerable' bash -c "echo this is a test"

If the system is vulnerable, the output will be:
Quote
vulnerable
this is a test
An unaffected (or patched) system will output:
Quote
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
 this is a test
