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. For the oldstable distribution (wheezy), this problem has been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u5. For the stable distribution (jessie), this problem has been fixed in version 1:9.9.5.dfsg-9+deb8u1. For the testing distribution (stretch) and the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your bind9 packages.
