A new exploit in the Bash command shell found in many versions of Unix, including Apple's OS X desktop operating system, makes Mac computers vulnerable to so-called 'Shell Shock' attacks, security researchers at RedHat discovered Thursday.
Though the exploit lets attackers run malicious scripts remotely, most people are not at risk unless they've manually allowed SSH access from remote connections or a web server running server side scripting.
Here's how you can check if you're vulnerable and what you can do in order to avoid 'Shell Shock' attacks on your system.
