Dear Mac OS X and GNU/Linux users,

It is highly recommended to update the bash shell program to protect against the Shellshock vulnerability.

Update on October 8, 2014: working patch for vulnerability CVE-2014-6277 for Ubuntu 14.04 LTS users is now available via a PPA repository (ppa:ubuntu-security-proposed/ppa).

More info here:

I presume this will also affect home routers running a modified version of GNU/Linux, if the router has bash installed…

Stock Android users are unaffected (for the time being), because the stock version of Android uses mksh instead of bash according to this link:

Non-jailbroken iPhones/iPads and non-rooted Android devices are not vulnerable to Shellshock.

However, jailbroken Android devices running Cydia or Cyanogen may have a vulnerable version of bash installed!

Ubuntu 14.04 LTS users:

Here is the code to run in a Terminal to see if your installed version of bash is vulnerable or not:

wget ; bash


Example of Terminal output:

$ sudo add-apt-repository ppa:ubuntu-security-proposed/ppa

$ sudo apt-get update

$ sudo apt-get dist-upgrade
