ISC BIND 9.3.0 < 9.9.8-P3 / 9.9.x-Sx < 9.9.8-S4 / 9.10.x < 9.10.3-P3 Multiple DoS

Medium Nessus Plugin ID 88385

Synopsis

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

Description

According to its self-reported version number, the installation of ISC BIND running on the remote name server is affected by multiple denial of service vulnerabilities :

- A denial of service vulnerability exists due to improper handling of certain string formatting options. An authenticated, remote attacker can exploit this, via a malformed Address Prefix List (APL) record, to cause an INSIST assertion failure and daemon exit.
(CVE-2015-8704)

- A denial of service vulnerability exists due to a failure to properly convert OPT records and ECS options to formatted text. A remote attacker can exploit this to cause a REQUIRE assertion failure and daemon exit.
Note that this issue only affects BIND 9.10.x.
(CVE-2015-8705)

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 BIND version 9.9.8-P3 / 9.9.8-S4 / 9.10.3-P3 or later.
