Look at this existing thread:

or just cut to the chase

Code: [Select]

env x='() { :;}; echo vulnerable' bash -c 'echo hello'
If vulnerable:

Code: [Select]

sudo apt-get update && sudo apt-get install bash

Ok I did this and this is what I got.

[email protected]:~$ env x='() { :;}; echo vulnerable' bash -c 'echo hello'
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
hello
[email protected]:~$

What does all that mean? and what do I do now?
Ok just ran this: dpkg -s bash | grep Version
and got this: Version: 4.3-7ubuntu1.1

So That means I am good. Now is that what is installed with all of LL 2.0? Cause I just installed Beryl onto that other laptop Is that ok?

Thanks.

Hello,
this is addressed/fixed by installing an available update either by doing -
Menu>Favorites>Install Updates
or
Menu>All>Install Updates
Whichever is your preferred method for opening updates.

Hi

Well I followed those instructions...
It said I was Vulnerable...
I did the update... and then just got "Hello"
So from the instructions I assume it's O.K

Check the version and see what it says.

Run this in terminal window: dpkg -s bash | grep Version
Paste results back in here.

There is no such thing as a vulnerable free operating system, it's technologically impossible. If I had a choice between windows that has vulnerabilities numbering in the millions vs linux that has a few, I know what side I'd rather be on.
