Description:Weak DNS ID generation allows response spoofing, DoS on parsing DNS request.
Affected:PERL : Net::DNS 0.59
 PERL : Net::DNS 0.60
CVE:CVE-2007-6341 (Net/DNS/RR/A.pm in Net::DNS 0.60 build 654, as used in packages such as SpamAssassin and OTRS, allows remote attackers to cause a denial of service (program "croak") via a crafted DNS response.)
 CVE-2007-3409 (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 (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.)
