As per ISC security bulletin *CVE-2009-4022* There is a problem with BIND 9
Cache Update From Additional Section
*Problem Description:* A Nameserver with DNSSEC validation enabled may
incorrectly add records to its cache from the additional section of
responses received during resolution of a recursive client query.This
behavior only occurs when processing client queries with checking disabled
(CD).It may occur both when requesting,and not when requesting,DNSSEC
records(DO).If the nameserver is authoritative-only this will not occur.
We have some business requirement where we need to reproduce the problem.
Could anyone advice a test case which I may use or direct me to some website
which could be useful for this purpose.
Any help will be appreciated.
