BIND version 8 generates cryptographically weak DNS query identifiers

Overview ISC BIND version 8 generates cryptographically weak DNS query IDs which could allow a remote attacker to poison DNS caches. Description The Berkeley Internet Name Domain BIND is a popular Domain Name System DNS implementation from Internet Systems Consortium ISC. Version 8 of the BIND...

Security Best Practice: Protect Yourself against DNS Cache Poisoning

DNS cache poisoning occurs when false DNS records are injected into a DNS server's cache tables. Once the cache tables have been altered, a remote attacker may inspect, capture or corrupt any information exchanged between hosts on the network. By poisoning a DNS server, a remote attacker could, f...

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...
