New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote name server is affected by multiple denial of service vulnerabilities.

Description

According to its self-reported version number, the instance of ISC BIND 9 running on the remote name server is 9.9.x prior to 9.9.9-P5 or 9.9.9-S7, 9.10.x prior to 9.10.4-P5, or 9.11.x prior to 9.11.0-P2. It is, therefore, affected by multiple denial of service vulnerabilities :

- A denial of service vulnerability exists in named due to a flaw that is triggered during the handling of a specially crafted answer packet in a response to an RTYPE ANY query. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit. Note that this vulnerability affects versions 9.4.0 to 9.6-ESV-R11-W1, 9.8.5 to 9.8.8, 9.9.3 to 9.9.9-P4, 9.9.9-S1 to 9.9.9-S6, 9.10.0 to 9.10.4-P4, and 9.11.0 to 9.11.0-P1. (CVE-2016-9131)

- A denial of service vulnerability exists in named in DNSSEC-enabled authoritative servers that is triggered during the handling of a query response that contains inconsistent DNSSEC information. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit. Note that this vulnerability affects versions 9.9.9-P4, 9.9.9-S6, 9.10.4-P4, and 9.11.0-P1. (CVE-2016-9147)

- A denial of service vulnerability exists in named due to a flaw that is triggered during the handling of a specially crafted answer that contains a DS resource record. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit. Note that this vulnerability affects versions 9.6-ESV-R9 to 9.6-ESV-R11-W1, 9.8.5 to 9.8.8, 9.9.3 to 9.9.9-P4, 9.9.9-S1 to 9.9.9-S6, 9.10.0 to 9.10.4-P4, and 9.11.0 to 9.11.0-P1. (CVE-2016-9444)

- A denial of service vulnerability exists in named in the nxdomain-redirect functionality that is triggered when handling a specially crafted query. An unauthenticated, remote attacker can exploit this to cause a REQUIRE assertion failure and daemon exit. Note that this vulnerability affects versions 9.9.8-S1 to 9.9.8-S3, 9.9.9-S1 to 9.9.9-S6, and 9.11.0-9.11.0 to P1.
(CVE-2016-9778)

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-P5 / 9.9.9-S7 / 9.10.4-P5 / 9.11.0-P2 or later.
