FreeBSD : FreeBSD -- Predictable query ids in named(8) (3de342fb-40be-11dc-aeac-02e0185f8d72)

When named8 is operating as a recursive DNS server or sending NOTIFY requests to slave DNS servers, named8 uses a predictable query id. Impact : An attacker who can see the query id for some requests sent by named8 is likely to be able to perform DNS cache poisoning by predicting the query id for...
