The RedHat security team have released details of a flaw which has been discovered in the BASH shell.


Updates should be coming rather quick for this issue so keep checking your systems for available security updates.


If you’d like to check if your system is currently vulnerable run the following command – courtesy of the Fedora Magazine

env x='() { :;}; echo OOPS' bash -c /bin/true

If your terminal outputs “OOPS” then you’re vulnerable, according to the article if you are running a patched bash the output will look like this –

bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x’
