Multiple DNS implementations vulnerable to cache poisoning

Overview
Deficiencies in the DNS protocol and common DNS implementations facilitate DNS cache poisoning attacks.
I. Description
The Domain Name System (DNS) is responsible for translating host names to IP addresses (and vice versa) and is critical for the normal operation of internet-connected systems. DNS cache poisoning (sometimes referred to as cache pollution) is an attack technique that allows an attacker to introduce forged DNS information into the cache of a caching nameserver. DNS cache poisoning is not a new concept; in fact, there are published …

The DNS server at IP address 202.188.0.132 is susceptible to a DNS cache poisoning attack. The server is not changing its source port, query id, or both, between queries.
