Details

Peter Johannes Holzer discovered that the Net::DNS Perl module had
predictable sequence numbers. This could allow remote attackers to
carry out DNS spoofing, leading to possible machine-in-the-middle attacks.
(CVE-2007-3377)

Steffen Ullrich discovered that the Net::DNS Perl module did not correctly
detect recursive compressed responses. A remote attacker could send a
specially crafted packet, causing applications using Net::DNS to crash or
monopolize CPU resources, leading to a denial of service. (CVE-2007-3409)
