Debian DLA-112-1 : bind9 security update

high Nessus Plugin ID 82096

Synopsis

The remote Debian host is missing a security update.

Description

This update fixes a denial of service vulnerability in BIND, a DNS server.

By making use of maliciously-constructed zones or a rogue server, an attacker could exploit an oversight in the code BIND 9 used to follow delegations in the Domain Name Service, causing BIND to issue unlimited queries in an attempt to follow the delegation.

This can lead to resource exhaustion and denial of service (up to and including termination of the named server process).

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
