ISC BIND 9.10.2 < 9.10.2rc2 Multiple Vulnerabilities

high Nessus Plugin ID 81487

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)

- Multiple flaws exist with GeoIP functionality. These flaws allow a remote attacker to cause a denial of service. Note that these issues only affect the 9.10.x branch. (CVE-2014-8680)

- 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)

- An error exists related to handling the 'geoip-directory' option in named.conf when running 'rndc reconfig' or 'rndc reload' that allows connections by unintended clients.

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 9.10.2rc2 or later.
