CVE-2002-2211

NameCVE-2002-2211
DescriptionBIND 4 and BIND 8, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.

Notes

- bind9 <not-affected> (does not send parallel queries)
Disabling recursion does not close all attack vectors.
Browser reflection attacks will still work.
Bind 8 design limitations that are only addressed in bind 9 are not
treated a security issues, DNS admins need to be aware what they are using
