RHEL 2.1 / 3 / 4 / 5 : bind (RHSA-2007:0740)

medium Nessus Plugin ID 25797

Synopsis

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

Description

Updated bind packages that fix a security issue are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols.

A flaw was found in the way BIND generates outbound DNS query ids. If an attacker is able to acquire a finite set of query IDs, it becomes possible to accurately predict future query IDs. Future query ID prediction may allow an attacker to conduct a DNS cache poisoning attack, which can result in the DNS server returning incorrect client query data. (CVE-2007-2926)

Users of BIND are advised to upgrade to these updated packages, which contain backported patches to correct this issue.

Solution

Update the affected packages.
