This is just a heads-up that if you're using the --dhcp-script option in dnsmasq, and the script you're calling is being interpreted by bash, then you're affected by the shellshock bug.
The bug allows execution of arbitrary code contained in the values of environment variables, and there are several variables in the environment inherited by the DHCP script whose values can be set directly by a DHCP client, so any DHCP client on your network (or elsewhere, if your firewall allows) can execute arbitrary shellcode, probably as root, with a simple DHCP request. The fix, of course, is to update bash.
