Shellshock is the media-friendly name for a security bug found in Bash, a command shell program commonly used on Linux and UNIX systems.
The bug is what’s known as a Remote Code Execution vulnerability, or RCE.
This means that someone who isn’t already logged on to your computer might be able to trick Bash into running a program that it wasn’t supposed to.
