RHSA-2008:0789 -- dnsmasq security update (Moderate)

oval:org.mitre.oval:def:29167

An updated dnsmasq package that implements UDP source-port randomization is now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 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.
