[Bug 247598] Re: dnsmasq might be vulnerable to recent DNS spoofing issue

[Thierry Carrez]

New debdiff with an additional check recommended by upstream :
"In the function nl_routechange() at the end of src/netlink.c, a check needs to be added to ensure that daemon->srv_save->sfd is non-NULL. This avoids a segfault. If it is NULL, just returning from the function is fine."

I checked that the resulting dnsmasq build still works as a DHCP and DNS
cache, and the extra patch looks non-disruptive, you should nevertheless
double-check it.
