+ There are broadly two sets of problems. The first is subtle errors
+ in dnsmasq's protections against the chronic weakness of the DNS
+ protocol to cache-poisoning attacks; the Birthday attack, Kaminsky,
+ etc.[...]
+ </p>
+ <p>
+ the second set of errors is a good old fashioned buffer overflow in
+ dnsmasq's DNSSEC code. If DNSSEC validation is enabled, an
+ installation is at risk.
