Red Hat has released a test how to check if your bash system is vulnerable.
The vulnerability is corrected with an update of 300kb.
I leave here the instructions for users of Linux (do not know if it works on OSX):
Start a terminal and enter the following command:
Code:env = x '() {:;}; Echo vulnerable 'bash c "echo this is a test"
if your system is vulnerable, this message is displayed:
vulnerable
this is a test
If this happens, check for and install updates for your system. Once resolved, rerun the command. If the problem is solved, this message is displayed:
bash: warning: x: ignoring function definition Attempt
bash: error importing function definition for `x '
this is a test
Always remember to upgrade your system, and pray to the Probe.

The vulnerability is partially corrected by the patch. See CVE-2014-7169.
FWIW the forum server has been patched against CVE-2014-6271.
