CVE-2007-6341 (2008-02-08)

Allows remote attackers to cause a denial of service (program "croak") via a crafted DNS response.

CVE-2007-3409 (2007-06-26)

Net::DNS before 0.60, a Perl module, allows remote attackers to cause a denial of service (stack consumption) via a malformed compressed DNS packet with self-referencing pointers, which triggers an infinite loop.

CVE-2007-3377 (2007-06-25)

Header.pm in Net::DNS before 0.60, a Perl module, (1) generates predictable sequence IDs with a fixed increment and (2) can use the same starting ID for all child processes of a forking server, which allows remote attackers to spoof DNS responses, as originally reported for qpsmtp and spamassassin.

Net::DNS is a perl implementation of a DNS resolver.

USAGE

Why does Net::DNS::Resolver::query() return undef when the ANSWER section is empty?

The short answer is, don't use query(). Net::DNS::Resolver::send() will always return the answer packet, as long as an answer was received.

The longer answer is that query() is modeled after the res_query() function from the libresolv C library, which has similar behaviors.
