Dnsmasq is lightweight DNS forwarder and DHCP server. It is designed to
provide DNS and, optionally, DHCP, to a small network.
The dnsmasq DNS resolver used a fixed source UDP port. This could have made
DNS spoofing attacks easier. dnsmasq has been updated to use random UDP
source ports, helping to make DNS spoofing attacks harder. (CVE-2008-1447)
All dnsmasq users are advised to upgrade to this updated package, that
upgrades dnsmasq to version 2.45, which resolves this issue.
