I finally had time to develop a PoC and confirm this on my own. A client
need only send a DHCPREQUEST for an IP address not on the same network
as dnsmasq. Eg:

1. dnsmasq listening on and giving IP addresses for 192.168.122.0/24
2. client requests IP address on another network, such as 192.168.0.1
3. dnsmasq 2.25 (and presumably earlier) crashes


It seems there is also a problem with newer dnsmasq that is very similar to
this:
http://bugs.gentoo.org/show_bug.cgi?id=232523

That problem appears to be pretty much the same thing, but affecting
versions 2.43 - 2.45

Did this ever get a CVE id?

I presume this new flaw will need one as well.

Thanks.
