Shellshock(Serious bash flaw. Affects Linux and Mac systems)

[Nexia]

Although there is no need for explaining what bash is to the average computer geek, for those who don't know, it's a widely used command interpreter (or in other words command-line shell program). The operating systems that use it include Linux, UNIX, and even Mac operating systems.

So a critical flaw has been discovered with bash in the way it handles environment variables, which can potentially allow a hijacker to remotely hijack an affected machine. Updating your system as soon as possible is advised (updates, even though incomplete, have been already rolled out for most Linux/Unix operating systems afaik, and are still expected to come out soon for the rest). Some experts are pointing out how this could be bigger than even Heartbleed.

(See the commands on that page for checking if you're vulnerable or not)

I do hope Apple is working on it's own update for this.

Update commands in some major Linux distributions. thanks Wohlstand

Spoiler: show

CentOS:

Code: Select all

sudo yum update

Debuan/Ubuntu/Mint

Code: Select all

sudo apt-get update
sudo apt-get upgrade

OpenSUSE

Code: Select all

sudo zypper update

ArchLinux

Code: Select all

sudo pacman update

etc.

In spite of rare instances like this one, Linux is way secure in comparison to Windows and it's numerous viruses =P

EDIT: So the name that caught on is "Shellshock" http://en.wikipedia.org/wiki/Shellshock ... are_bug%29
