Protocol TCP,UDP
Class DNS
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 9.10.x prior to 9.10.4-P6 are affected by a denial of service vulnerability in the query_find() function in query.c that is triggered when using DNS64 and RPZ simultaneously for rewriting query responses. An unauthenticated, remote attacker can exploit this to cause an INSIST assertion failure or a NULL pointer read, resulting in a termination of the service.

* Note: This check solely relied on the banner of the remote DNS server to assess this vulnerability, so this might be a false positive.
