3. Problem description:

Net::DNS is a collection of Perl modules that act as a Domain Name System

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)

Users of Net::DNS should upgrade to this updated package, which contains
backported patches to correct this issue.
