ISC BIND 9 DNS64 Handling DoS (CVE-2012-5689)

medium Nessus Plugin ID 106136

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 9.8.5 / 9.9.3 or later. Alternatively, disable DNS64 functionality via configuration options.
