3. Problem 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.
4. Solution:
Before applying this update, make sure that all previously-released
