Description

VMware has acknowledged some vulnerabilities in VMware vMA, which can be exploited by malicious people to poison the DNS cache.

1) A vulnerability is caused due to BIND caching CNAME or DNAME records of a response without proper DNSSEC verification.

2) An error within the DNSSEC NSEC/NSEC3 validation mechanism could lead to bogus NXDOMAIN responses being cached as correctly validated.

For more information:
SA38219


Solution
Do not use bind.
