Synopsis

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

Description

According to its self-reported version number, the remote installation of BIND is affected by multiple denial of service 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, could potentially cause the service to issue unlimited queries leading to resource exhaustion. (CVE-2014-8500)

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to BIND version 9.9.6-P1 / 9.10.1-P1 or later.
