If you have a Linux or Mac computer (yes Macs are computers), you might have a level 10 (out of 10) vulnerability called Shellshock. This vulnerability would allow attackers to inject code into your machine. This could lead to serve malicious attacks.
The vulnerability was discovered by by the open source company, Red Hat. They were having trouble on their servers and discovered this. They reported it right away.
You can test your system by running this test command from Terminal:
env x='() { :;}; echo vulnerable' bash -c 'echo hello'
If you’re not vulnerable, you’ll get this result:
bash: warning: x: ignoring function definition attempt bash: error importing function definition for `x' hello
If you are vulnerable, you’ll get:
vulnerable hello
You can also check the version of bash you’re running by entering:
bash --version
If you get version 3.2.51(1)-release as a result, you’ll need to update. Many Linux distributions already have patches available, so you can follow these instructions to update your system. Mac users are still waiting for a patch, but you can update bash manually using this guide. (LifeHacker)
I hope most of my iZombie (Apple Fanatics) friends check this out. This is a real threat to you. For some of you, it is time to step away from the Kool-Aide that this can’t happen to you because you have a Mac. It is okay. Take a deep breath. If you need assistance running command lines or checking it out, let me know.
Stay Geeky and Stay Safe My Friends!
