Posted by Benjamin D. Thomas   
Ubuntu 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 man-in-the-middle attacks.
=========================================================== 
Ubuntu Security Notice USN-483-1              July 11, 2007
libnet-dns-perl vulnerabilities
CVE-2007-3377, CVE-2007-3409
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  libnet-dns-perl                          0.53-2ubuntu1

Ubuntu 6.10:
  libnet-dns-perl                          0.57-1ubuntu1

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Details follow:

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 man-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)
