Major vulnerability in bash

Hello Guys,

I read some blogs and according to it bash susceptible to environment variables code injection attack.
I think we should update our bash with latest patch of bash available.
my old bash version for centos 6.5 is 
[root@centos-test ~]# rpm -q bash
bash-4.1.2-15.el6_4.x86_64
[root@centos-test ~]# env x='() { :;}; echo problem' bash -c /bin/true
problem
if you gets output as a problem that means your bash version needs to be updated with latest patch.

Then I updated it and now its
[root@centos-test ~]# rpm -q bash
bash-4.1.2-15.el6_5.1.x86_64
[root@centos-test ~]# env x='() { :;}; echo problem' bash -c /bin/true
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'

if you gets output as above that means your bash version is fine.
