Test ID:1.3.6.1.4.1.25623.1.0.117784
Category:Denial of Service
Title:ISC BIND DoS Vulnerability (CVE-2016-2088)
Summary:ISC BIND is prone to a denial of service (DoS) vulnerability.
Description:Summary:
ISC BIND is prone to a denial of service (DoS) vulnerability.

Vulnerability Insight:
BIND 9.10 has preliminary support for DNS cookies (or source
identity tokens), a proposed mechanism designed to allow lightweight transaction security between
a querying party and a nameserver. An error in the BIND code implementing support for this
optional feature permits a deliberately misconstructed packet containing multiple cookie options
to cause named to terminate with an INSIST assertion failure in resolver.c if DNS cookie support
is enabled in the server. Only servers with DNS cookie support enabled at build time can be
affected by this defect. In servers which do not have DNS cookie support selected, any cookies
encountered will be ignored as unknown option types.

Vulnerability Impact:
Servers which are built with DNS cookie support enabled are
vulnerable to denial of service if an attacker can cause them to receive and process a response
that contains multiple cookie options.

Affected Software/OS:
ISC BIND version 9.10.x through 9.10.3-P3.

Solution:
Update to version 9.10.3-P4 or later.

CVSS Score:
4.3
