high Nessus Plugin ID 55534
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 may be affected by a denial of service vulnerability.

Description

According to its self-reported version number, the remote installation of BIND is potentially affected by a denial of service vulnerability. If an attacker sends a specially crafted request to a BIND server it may cause the name server process to crash.

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

Solution

Upgrade to BIND 9.6-ESV-R4-P3 / 9.7.3-P3 / 9.8.0-P4 or later.
