Thanks for the info.

Has anyone tried this with an OS X client to see if it behaves like the Linux system in the article? I know OS X bash is vulnerable to the exploit, but I don't know if their DHCP system handles environment variables in an exploitable way.

OS X doesn't use Bash for configuring DHCP, so it's not vulnerable. All of that is done in the kernel on Macs.
