RHEL 3 / 5 : perl-Net-DNS (RHSA-2007:0674)

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

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.

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.
