ISC BIND 9 < 9.9.10-P2 / 9.9.10-S3 / 9.10.5-P2 / 9.10.5-S3 / 9.11.1-P2 Multiple Vulnerabilities

Synopsis

The remote name server is affected by multiple vulnerabilities.

Description

According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is 9.9.x prior to 9.9.10-P2 or 9.9.10-S3, 9.10.x prior to 9.10.5-P2 or 9.10.5-S3, or 9.11.x prior to 9.11.1-P2. It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in the Transaction Signature (TSIG) authentication implementation when handling received messages. An unauthenticated, remote attacker can exploit this, via a specially crafted request packet, to circumvent TSIG authentication of AXFR requests. Note that to exploit this issue the attacker must be able to send and receive messages to an authoritative DNS server and have knowledge of a valid TSIG key name.
(CVE-2017-3142)

- A flaw exists in the Transaction Signature (TSIG) authentication implementation when handling messages.
An unauthenticated, remote attacker can exploit this to manipulate BIND into accepting an unauthorized dynamic update. Note that to exploit this issue the attacker must be able to send and receive messages to an authoritative DNS server and have knowledge of a valid TSIG key name for the zone and service being targeted.
(CVE-2017-3143)

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

Solution

Upgrade to ISC BIND version 9.9.10-P2 / 9.9.10-S3 / 9.10.5-P2 / 9.10.5-S3 / 9.11.1-P2 or later.
