| Detailed Description |
ISC BIND (Berkeley Internet Name Daemon) is a server utility that implements the DNS (domain name service) protocol. It is widely used on the Internet. According to its version number, the installation of ISC BIND on the remote name server is potentially affected by a denial of service vulnerability due to a REQUIRE assertion flaw that occurs while handling TKEY queries. A remote attacker can exploit this by using a specially crafted TKEY query to crash the daemon.
* Note: This check solely relied on the banner of the remote DNS server to assess this vulnerability, so this might be a false positive.
