echo vulnerable
Even though most people are now aware of the Shellshock security problem on the bash shell, here is a test to check whether your Unix system is at risk:
env x='() { :;}; echo vulnerable' bash -c 'echo hello'
if the prompt returns vulnerable, it means the system is vulnerable and needs to be upgraded with the proper security patch… For instance running
sudo apt-get update && sudo apt-get install --only-upgrade bash
for Debian/Ubuntu versions. Check Apple support page for Apple OS.

Reblogged this on In Ken's Head and commented:
Note to self to test at home later.
But I also can’t help wondering, with all of the breaches, loopholes, backdoors and revelations these days, is it possible to be digitally safe and secure at all any longer?

Was there ever such a time (where one felt safe and secure)?!

Fair point. Ignorance is bliss I suppose, and there was merely a time in the past when I was more ignorant.
