ISC BIND 9 Multiple DoS

Medium Nessus Plugin ID 89999

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 running on the remote name server is affected by multiple denial of service vulnerabilities :

- A denial of service vulnerability exists in files resolver.c and db.c when handling DNAME resource signatures. An unauthenticated, remote attacker can exploit this, via a crafted query that generates a response containing a signature record, to cause an assertion failure and daemon exit. (CVE-2016-1286)

- A denial of service vulnerability exists in resolver.c when DNS cookies are enabled. An unauthenticated, remote attacker can exploit this, via a malformed cookie with more than one cookie option, to cause an INSIST assertion failure and daemon exit. (CVE-2016-2088)

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 9.9.8-P4 / 9.9.8-S6 / 9.10.3-P4 or later.
Note that version 9.9.8-S6 is a preview version of BIND provided exclusively to ISC Support customers. Additionally, the fix for CVE-2016-2088 is only available in version 9.10.3-P4.
