Your site currently (2pm EST) lists two exploits, but omits a third variant which "Mitchell" posted in your site's comments 8 hours ago. I've tested two fully updated Ubuntu servers. Both are not vulnerable to the two exploits you posted, but both are vulnerable to the exploit listed in Mitchell's comment. I suggest you post Mitchell's variant prominently as well. The two exploits you've posted: 1. env x='() { :;}; echo vulnerable' bash -c "echo this is a test" 2. env X='() { (a)=>\' bash -c "echo date"; cat echo The third variant Mitchell posted in his comment: 3. env -i X=' () { }; echo hello' bash -c 'date' The systems I've tried these on both have been updated with "sudo apt-get update"; "sudo apt-get dist-upgrade". The systems are: A. Ubuntu 12.04.5 LTS, running Bash version 4.2.25(1)-release (x86_64-pc-linux-gnu) B. Ubuntu 10.04.4 LTS, running version 4.1.5(1)-release (x86_64-pc-linux-gnu)
