FreeBSD : dns/bind9* -- Heavy DNSSEC Validation Load Can Cause a 'Bad Cache' Assertion Failure (0bc67930-d5c3-11e1-bef6-0024e81297ae)

ISC reports : High numbers of queries with DNSSEC validation enabled can cause an assertion failure in named, caused by using a 'bad cache' data structure before it has been initialized. BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broke...

FreeBSD -- named(8) DNSSEC validation Denial of Service

Problem description: BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broken chain of trust. Under high query loads, when DNSSEC validation is active, it is possible for a condition to arise in which data from this cache of failing queries...

dns-nsec3-enum NSE Script

Tries to enumerate domain names from the DNS server that supports DNSSEC NSEC3 records. The script queries for nonexistant domains until it exhausts all domain ranges keeping track of hashes. At the end, all hashes are printed along with salt and number of iterations used. This technique is known...

dns/bind9* -- zero-length RDATA can cause named to terminate, reveal memory

ISC reports: Processing of DNS resource records where the rdata field is zero length may cause various issues for the servers handling them. Processing of these records may lead to unexpected outcomes. Recursive servers may crash or disclose some portion of memory to the client. Secondary servers...
