RHEL 5 : bind (RHSA-2009:1620)

Low Nessus Plugin ID 42946

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated bind packages that fix one security issue are 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.

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Michael Sinatra discovered that BIND was incorrectly caching responses without performing proper DNSSEC validation, when those responses were received during the resolution of a recursive client query that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries. (CVE-2009-4022)

All BIND users are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing the update, the BIND daemon (named) will be restarted automatically.

Solution

Update the affected packages.
