[App_rpt-users] NEW Security Issues

Here is how you should check to see if you are vulnerable and odds are you
ARE.

~# env x='() { :;}; echo vulnerable' bash -c "echo this is a test"

If the system is vulnerable, the output is:

vulnerable
this is a test

It is far easier to upgrade bash and all OS distros now have a patch.

Cool. I'll give it a go before a reload. Whenever I do a server build, I
take copious notes so I can duplicate all the steps,.. just time.

Thanks much!

ACID unless there is a way to "undo" the yum update. (sigh!)

Sorry I did not qualify that. The way to update centos is 

yum update bash

The current update is:

Updated:
  bash.i386 0:3.2-33.el5.1

This should not require any recompiles. If you have any current bash jobs
running you would have to stop and restart them to use the new code or just
reboot.

The increase in recent hack attempts are the result of the resent knowlage
of a fundamental bug in bash.

It was not a big deal till someone published the flaw before some patches
could be issued.

Some folks set-ups are vulnerable. If you run HTTP, you certainly are.

Just a FYI...

SHELLSHOCK  - this is bigger and older than heartbleed.

It is a very big deal for "all" linux systems running http.

http://seclists.org/oss-sec/2014/q3/650       

to check your version of bash, type

cd /bin

bash --version

our acid installs should be at 3.2

Remote ssh devices are possibly at risk.

Current patches may not be entirely effective.

Much more to be known about this.

google shellshock for more info.
