RHEL 5 : dnsmasq (RHSA-2008:0789)

This script is Copyright (C) 2008-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing a security update.

Description :

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.

All dnsmasq users are advised to upgrade to this updated package, that
upgrades dnsmasq to version 2.45, which resolves this issue.
