Overview
ISC BIND 9 contains a vulnerability that may allow a remote, unauthenticated attacker to create a denial-of-service condition.
Description
The Berkeley Internet Name Domain (BIND) is a popular Domain Name System (DNS) implementation from Internet Systems Consortium (ISC). It includes support for dynamic DNS updates as specified in IETF RFC 2136. BIND 9 can crash when processing a specially-crafted dynamic update packet. ISC notes that this vulnerability affects all servers that are masters for one or more zones and is not limited to those that are configured to allow dynamic updates. ISC also indicates that the attack packet has to be constructed for a zone for which the target system is configured as a master; launching the attack against slave zones does not trigger the vulnerability. |
Impact
By sending a specially-crafted dynamic update packet to a BIND 9 server, a remote, unauthenticated attacker can cause a denial of service by causing BIND to crash. |

Affected
Vendor Statement
==========================
NIXU ADVISORY ON VU#725188
==========================
=====================
Nixu NameSurfer Suite
=====================
All Nixu NameSurfer versions ship with a proprietary primary DNS server is
not affected by VU#725188. Therefore, when Nixu NameSurfer is run as the
primary DNS server, no action is required to protect the master DNS server
against this threat.
Nixu NameSurfer Suite 6.5.2 ships with an optional companion BIND 9.6.1
server that can be installed on the same server running Nixu NameSurfer
Suite. If the companion BIND 9.6.1 server has been activated at install and
is used to run localhost (127.0.0.1) as a master zone, Nixu recommends
either of the following approaches:
1) the master zone on localhost BIND is disabled
2) the localhost BIND is patched to version 9.6.1-P1
Please note that a failure in the localhost BIND due to the vulnerability
outlined in VU#725188 does not pose any threat to authoritative DNS zones
for which Nixu NameSurfer Suite is the master, i.e. Nixu NameSurfer primary
DNS server will continue to serve the (remote) secondary DNS servers even if
the optional local BIND server failed.
=============================
Nixu Secure Name Server (SNS)
=============================
Nixu SNS secondary server instances hosting slave copies of master zones
managed in Nixu NameSurfer primary are not affected by VU#725188.
