The ISC BIND nameserver contains a vulnerability that could allow a remote attacker to cause a denial of service.
According to ISC:
Adding certain types of signed negative responses to cache doesn't clear any matching RRSIG records already in cache. A subsequent lookup of the cached data can cause named to crash (INSIST).
A remote attacker could cause the name server on an affected system to crash. ISC notes that this vulnerability affects recursive nameservers irrespective of whether DNSSEC validation is enabled or disabled.
