New! Plugin Severity Now Using CVSS v3

Synopsis

The remote name server is affected by a memory exhaustion vulnerability

Description

According to its self-reported version number, the installation of ISC BIND running on the remote name server is affected by a memory exhaustion vulnerability. A server is potentially vulnerable if it accepts zone data from another source, as no limit is currently placed on zone data size.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Follow guidance provided by ISC advisory.
