dnsmasq -- DNS cache poisoning, and DNSSEC buffer overflow, vulnerabilities

Simon Kelley reports:

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.[...]

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.
