Quick BIND question

[jmitchel <jmitchel%bigjar.com@localhost>]

Hello,

I know this is a somewhat annoying question, because it's very broad and 
the server's out of date, but am I going to get in trouble using the 
version of BIND that came with NetBSD 6.1.4. Here's the info:

Karma:/etc/namedb# uname -a
NetBSD Karma 6.1.4 NetBSD 6.1.4 (GENERIC) i386
Karma:/etc/namedb# named -V
BIND 9.9.2-P1 built with defaults
using OpenSSL version: OpenSSL 1.0.1g 7 Apr 2014

The box will be answering queries from a cached version of the Windows 
DNS domain, and will also be used to forward all non-local lookups to 
OpenDNS. It is behind a SonicWall firewall and there isn't any direct 
access to port 53 (either TCP or UDP) from the Internet. What are the 
odds the server will be okay?

I know I should just install the latest version, but I'm under the gun 
as we've just realized that there are about 400 "Malware" DNS queries 
per day and I'm worried about what's installed on what computers and 
want to know which ones are infected ASAP.

Thanks in advance for reading and any help you can provide.
