It looks like my CVM's running are vulnerable to the now hyped-up CVE-2014-6271. What is the official Nutanix stance on remediating the vulnerability - should I wait for an NOS hotfix or can I pull down the relevant CentOS patch?

Hello, It is not supported to apply patches from other sources. Also, please note the field advisory that went out for Shellshock: FIELD ADVISORY #0023 - - posted on our site as well.. Thanks!

It may be possible but it's definitely not supported/recommended.

Is it possible to apply the official CentOS bash not vulnerable packeage on the CVM?

You can check it with something like:

env VAR='() { :;}; echo I am vulnerable!' bash -c "echo Bash Test"

Just finish to fix a lot of CentOS boxes with bash-4.1.2-15.el6_5.2.x86_64

Regardless of the patch, keeping managment seperated is the first step. You can also use iptables on the CVM to restrict traffic.

Per conversation with my SRE, it sounds like Nutanix will be pulling the hotfix down from CentOS and porting it into an upcoming release. Specific timing should be disclosed later today.
