URGENT update BASH - big security issue
Sep 25, 2014 · 1 minute readCategory: security
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.
