    contrib/bind9/bin/named client.c 
    contrib/bind9/lib/dns dispatch.c 
    contrib/bind9/lib/dns/include/dns dispatch.h 
  Update to 9.3.4-P1, which fixes the following:
  The DNS query id generation is vulnerable to cryptographic
  analysis which provides a 1 in 8 chance of guessing the next
  query id for 50% of the query ids. This can be used to perform
  cache poisoning by an attacker.
  This bug only affects outgoing queries, generated by BIND 9 to
  answer questions as a resolver, or when it is looking up data
  for internal uses, such as when sending NOTIFYs to slave name
  All users are encouraged to upgrade.
