By Amir Zali | April 01, 2016
In this second part article, we analyze two recent vulnerabilities in ISC BIND identified as CVE-2016-1286 and CVE-2016-2088. Based on advisories, these bugs can be triggered using a malformed DNAME record (CVE-2016-1286) or an OPT COOKIE records (CVE-2016-2088).
These two bugs share the same attack scenario that can only be triggered when a BIND server makes a request and then receives a malformed response. Based on this requirement, recursive servers are at highest risk to this attack, because it’s not straightforward to ask an authoritative-only server to make a DNS request.

The Internet Systems Consortium just released a couple of days ago a new patch (version 9.10.3-P4) to fix some issues in the most popular DNS server software in the world.
The release note is available at https://kb.isc.org/article/AA-01363/81/BIND-9.10.3-P4-Release-Notes.html
In this series of two articles, we will detail our investigation of these vulnerabilities and how we were able to protect our customers by deploying widely our detection.
ISC released a patch for the BIND rndc control channel DoS vulnerability (CVE-2016-1285). According to ISC, this vulnerability is due to an assertion failure in the application called named when it’s handling a malformed packet

CVE-2016-2088 bind: malformed packet containing multiple cookie options can trigger assertion failure
The following flaw, reported by ISC, was found in BIND 9.10:
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 encou
