Synopsis

Moderate: perl-Net-DNS security update

Type/Severity

Security Advisory: Moderate

Topic

Updated perl-Net-DNS packages that correct two security issues are now
available for Red Hat Enterprise Linux 3 and 5.

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

Description

Net::DNS is a collection of Perl modules that act as a Domain Name System
(DNS) resolver.

A flaw was found in the way Net::DNS generated the ID field in a DNS query.
This predictable ID field could be used by a remote attacker to return
invalid DNS data. (CVE-2007-3377)

A denial of service flaw was found in the way Net::DNS parsed certain DNS
requests. A malformed response to a DNS request could cause the application
using Net::DNS to crash or stop responding. (CVE-2007-3409)

Users of Net::DNS should upgrade to these updated packages, which contain
backported patches to correct these issues.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
