Breno Silveira Soares of Servico Federal de Processamento de Dados (SERPRO) discovered that the BIND DNS server is prone to a denial of service vulnerability. A remote attacker who can cause a validating resolver to query a zone containing specifically constructed contents can cause the resolver to terminate with an assertion failure, resulting in a denial of service to clients relying on the resolver.
