ISC BIND 9 DNS64 Handling DoS

high Nessus Plugin ID 63166

Synopsis

The remote name server is prone to a denial of service attack.

Description

According to its self-reported version number, the remote installation of BIND can be forced to crash via maliciously crafted DNS requests.

Note that this vulnerability only affects installs using the 'dns64' configuration option. Further note that Nessus has only relied on the version itself and has not attempted to determine whether or not the install is actually affected.

Solution

Upgrade to BIND 9.8.4-P1 / 9.9.2-P1 or later. Alternatively, disable DNS64 functionality via configuration options.
