| 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, BIND version 9.9.6-S2 is affected by a denial of service vulnerability due to an error relating to DNSSEC validation and the managed-keys feature. A remote attacker can trigger an incorrect trust-anchor management scenario in which no key is ready for use, resulting in an assertion failure and daemon crash.
* Note: This check solely relied on the banner of the remote DNS server to assess this vulnerability, so this might be a false positive.
