NerdytData patches Shellshock in a single crawl

Anyone who's running their web server as a user with enough privileges to run package installs unattended is probably in for a worse fate than an unexpected bash update, I imagine...
Also, their apt-get command is incorrect. apt-get update updates the local repo cache, apt-get -yy install bash will upgrade the bash package. So now they're down to two of the four machines, the ones that run RHEL.
All their exercise has done is to land their crawler IPs on some lists of IPs attempting to exploit this vulnerability. I don't think that will help them any with their business.
env x='() {.:;.} ; echo yo'
*line 0: syntax error near unexpected token `{.:'*
It should be: env x='() { :;} ; echo yo'
Better luck next time.
