URGENT update BASH - big security issue

Shell Shock is a BASH exploit that can allow the running of arbitrary commands on Linux servers.

This is a newly discovered bug and affects a very large number of servers.

There is a patch, you should ensure that your server’s BASH version is updated ASAP.

Centos, Redhat etc

yum clean all; yum -y update bash

Ubuntu, Debian etc

apt-get install --only-upgrade bash

To check if you are vulnerable, you can run this code:

env X="() { :;} ; echo VULNERABLE" /bin/sh -c "echo completed"

If you see VULNERABLE then you need to update BASH.
