Most major distros have issued a patched version of Bash - use apt-get, yum, etc.
For now, there isn’t really an easy mitigation - unless you know for sure that you don’t have any websites that use CGI, and can simply disable mod_cgi. Keep an eye out for an updated version of Bash, or other mitigations. If you run a Linux/*nix Apache web server, or if you use someone else’s server that also has Apache installed, you are vulnerable. The situation is probably similar for Android: It has a vulnerable version of Bash, but actually exploiting it is probably quite hard.
Apple has already issued a statement saying that normal OS X users, despite having a vulnerable version of Bash, are not vulnerable. This doesn’t mean that your system is vulnerable, though. If “you might be vulnerable” pops up, your system has an exploitable version of Bash installed.

Shellshock also has the potential to be turned into a worm - a self-replicating piece of code that automatically propagates to all Shellshock-vulnerable systems, potentially causing untold damage. In simple terms, this means that it’s now relatively simple for anyone to gain unauthorized access to a large portion of the world’s computers, and download/extract a wide variety of sensitive details. Unlike Heartbleed, which was quite hard to exploit properly, Shellshock can be exploited with just a couple of lines of code, giving just about anyone the ability to run arbitrary code on an affected computer. It potentially affects around half of all websites on the internet (around 500 million), and millions or billions more internet-connected devices such as routers, smartphones. There’s a new internet-crippling zero-day vulnerability in town called Shellshock. The original story, which is still accurate and informative, remains below. The patched version of Bash which fixed the initial Shellshock vulnerability (CVE-2014-6271) does not protect you against this new vulnerability (CVE-2014-6277 and CVE-2014-6278).

It is unrelated to the first Shellshock vulnerability, but it is essentially the same deal: It’s very easy to exploit, and allows attackers to execute arbitrary code on a remote computer. I was researching a problem that had nothing to do with OS X today at one of my favorite exploit sites and I found something unexpected: Mac OS X < 10.4.7 Mach Exception Handling Local Root Exploit Mac OS X < 10.4.7 Mach Exception Handling Local Exploit (10.3.x 0day) I download the source code and gave it an examination. Updated 8:10am, September 29: Another remote code execution vulnerability has been found in Bash.
