ISC BIND 9 < 9.9.9-P8 / 9.9.9-S10 / 9.9.10rc3 / 9.10.4-P8 / 9.10.5rc3 / 9.11.0-P5 / 9.11.1r3 Multiple Vunlerabilities

High Nessus Plugin ID 99478

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 9.9.9-P8 or 9.9.9-S10, 9.10.x prior to 9.10.4-P8, or 9.11.x prior to 9.11.0-P5. It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists in DNS64 when handling certain queries for synthesized records. An unauthenticated, remote attacker can exploit this, via a specially crafted query, to cause an assertion failure, resulting in DNS64 terminating. Note that issue applies if the server is configured to use DNS64 and if the option 'break-dnssec yes;' is in use. (CVE-2017-3136)

- A denial of service vulnerability exists when handling specially crafted responses containing CNAME or DNAME resource records that are ordered in specific ways. An unauthenticated, remote attacker can exploit this, via responses sent in an unusual order, to cause an assertion failure, resulting in the resolver terminating. (CVE-2017-3137)

- A denial of service vulnerability exists when handling a NULL command string sent to the named control channel.
An authenticated, remote attacker can exploit this to cause an REQUIRE assertion failure, resulting in the named daemon exiting. Note that the BIND control channel is not configured by default. (CVE-2017-3138)

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 9.9.9-P8 / 9.9.9-S10 / 9.9.10rc3 / 9.10.4-P8 / 9.10.5rc3 / 9.11.0-P5 / 9.11.1rc3 or later.
