CVE-2008-1447
The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1,
9.4.2-P1, and 9.3.5-P1, (2) Microsoft DNS in Windows 2000 SP4, XP SP2
and SP3, and Server 2003 SP1 and SP2, and other implementations allow
remote attackers to spoof DNS traffic via a birthday attack that uses
in-bailiwick referrals to conduct cache poisoning against recursive
resolvers, related to insufficient randomness of DNS transaction IDs
and source ports, aka 'DNS Insufficient Socket Entropy Vulnerability'
or 'the Kaminsky bug.'");
