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 affected by multiple vulnerabilities.

Description

According to its self-reported version number, the instance of ISC BIND running on the remote name server is 9.x.x prior to 9.9.10-P1, 9.10.x prior to 9.10.5-P1, or 9.11.x prior to 9.11.1-P1. It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists when processing Response Policy Zone (RPZ) rule types. An unauthenticated, remote attacker can exploit this, via a specially crafted query, to cause an infinite loop condition that degrades the server's functionality.
(CVE-2017-3140)

- A privilege escalation vulnerability exists in the BIND installer for Windows due to using an unquoted service path. A local attacker can exploit this to gain elevated privileges provided that the host file system permissions allow this. Note that non-Windows builds and installations are not affected. (CVE-2017-3141)

Solution

Upgrade to ISC BIND version 9.9.10-P1 / 9.9.10-S2 / 9.10.5-P1 / 9.10.5-S2 / 9.11.1-P1 or later. Note that BIND 9 versions 9.9.10-S2 and 9.10.5-S2 are available exclusively for eligible ISC Support customers.
