Knot DNS 1.5.2 Incremental Zone Transfer (IXFR) DoS

high Nessus Plugin ID 78890
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 DNS server is potentially affected by a denial of service vulnerability.

Description

The remote host is running Knot DNS version 1.5.2. It is, therefore, affected by an error that could allow certain Incremental Zone Transfer (IXFR) messages to crash the server.

Solution

Update to version 1.5.3 or later.
