A vulnerability in the bash scripting language was disclosed on 24/9/2014. You can read about it here
http://seclists.org/oss-sec/2014/q3/650
All SARK variants, except SARK500, shipped on or before 25/9/2014 have this vulnerability.
You can check any bash on any site using the following command
env X="() { :;} ; echo busted" `which bash` -c "echo completed"
If the command returns the word "busted" then the bash version has the vulnerability.
To fix your SARK site do the following

apt-get update apt-get install bash
SME Server 8.0 based releases
yum update bash
Other releases
If you have an smeserver release prior to SME 8 then you must upgrade to smeserver 8.0 and apply the above update.
