Synopsis

The remote name server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the remote installation of BIND is potentially affected by multiple vulnerabilities :

- A flaw exists within the Domain Name Service due to an error in the code used to follow delegations. A remote attacker, with a maliciously-constructed zone or query, can cause the service to issue unlimited queries, resulting in resource exhaustion. (CVE-2014-8500)

- A denial of service vulnerability exists due to an error relating to DNSSEC validation and the managed-keys feature. A remote attacker can trigger an incorrect trust-anchor management scenario in which no key is ready for use, resulting in an assertion failure and daemon crash. (CVE-2015-1349)

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 9.9.7rc2 or later.
