| Description: | An updated dnsmasq package that implements UDP source-port randomizationis now available for Red Hat Enterprise Linux 5.This update has been rated as having moderate security impact by the RedHat Security Response Team.Dnsmasq is lightweight DNS forwarder and DHCP server. It is designed toprovide DNS and, optionally, DHCP, to a small network.The dnsmasq DNS resolver used a fixed source UDP port. This could have madeDNS spoofing attacks easier. dnsmasq has been updated to use random UDPsource ports, helping to make DNS spoofing attacks harder. (CVE-2008-1447)All dnsmasq users are advised to upgrade to this updated package, thatupgrades dnsmasq to version 2.45, which resolves this issue. |
