RHEL 5 : bind (RHSA-2007:0057)

high Nessus Plugin ID 25313

Synopsis

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

Description

Updated bind packages that fix a security issue and a bug 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.

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

A flaw was found in the way BIND processed certain DNS query responses. On servers that had enabled DNSSEC validation, this could allow a remote attacker to cause a denial of service. (CVE-2007-0494)

A use-after-free flaw was found in BIND. On servers that have recursion enabled, this could allow a remote attacker to cause a denial of service. (CVE-2007-0493)

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

Solution

Update the affected packages.
