Protocol 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, the installation of ISC BIND on the remote name server is potentially affected by a denial of service vulnerability due to improper parsing of incorrect class attributes in db.c. An unauthenticated, remote attacker can exploit this, via a malformed class attribute, to trigger a REQUIRE assertion failure, resulting in a denial of service condition.

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