RHSA-2008:0789 - Security Advisory
Synopsis
Moderate: dnsmasq security update
Type/Severity
Security Advisory: Moderate
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
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.
Description
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.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
