Code injection

The 1 NSIDSHUFFLEONLY and 2 NSIDUSEPOOL PRNG algorithms in ISC BIND 8 before 8.4.7-P1 generate predictable DNS query identifiers when sending outgoing queries such as NOTIFY messages when answering questions as a resolver, which allows remote attackers to poison DNS caches via unknown vectors...

BIND 8 EOL and BIND 8 DNS Cache Poisoning (Amit Klein, Trusteer)

BIND 8 EOL and BIND 8 DNS Cache Poisoning Note: this is a different attack from BIND 9 DNS cache poisoning. I discovered a new weakness in BIND 8 DNS server which enables "DNS Forgery Pharming". An attacker can remotely poison the cache of any BIND 8 caching DNS server and force users who use thi...
