ISC BIND 9 RDATA Section Handling DoS

high Nessus Plugin ID 69106
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.


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


According to its self-reported version number, the remote installation of BIND can be forced to crash via specially crafted queries containing malformed 'rdata' contents.

Note that Nessus has only relied on the version itself and has not attempted to determine whether or not the install is actually affected.

Further note that this vulnerability is being actively exploited at the time of this writing.


Upgrade to BIND version 9.9.3-S1-P1 / 9.9.3-P2 / 9.8.5-P2 or later, or apply the vendor-supplied patch.

In the case of development branches, such as 9.8.6rc1 / 9.9.4rc1 / 9.9.4-S1rc1, no patch is currently available.
