VID 19055
Severity 40
Port 79
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, the installation of ISC BIND on the remote name server is potentially affected by a denial of service vulnerability in file resolver.c when DNS cookies are enabled. An unauthenticated, remote attacker can exploit his, via a malformed packet with more than one cookie option, to cause an INSIST assertion failure and daemon exit.

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