KAMINSKY vulnerability !!

At 1st I assumed an exploit after looking at the version of bind I was
using, which was a beta, I noticed that there was some talk of the beta
version crashing and the solution was to go to P1. Looking back on it I did
an emergency upgrade to the beta because of the kaminsky problem. Since both
our name server are chrooted and have never gave us any issues I slowly
forgot about the fact that I was using the beta version. Remember not until
today has the version giving me any issues.
As far as getting away with the version, I looked at the ISC site and
noticed that BIND 9.4.3-P5 doesn't seem to have an known issues. Since I'm
running BIND on an older server, centos 4.8 with one gig of ram, I decided
to compile 9.4.3-P5 instead of the newer version because some of my libs/etc
might be older and therefore not supported by the latest release. I need to
get these name servers up and running and being stable fast.

A) Why do you assume an exploit at all? Hopefully you understand that
the vast majority of software crashes in the world are triggered by
B) From the www.isc.org website:
"BIND 9.4-ESV-R1 is now available. BIND 9.4-ESV-R1 is revision 1 of the
extended release version for BIND 9.4. It is recommended that all BIND
9.4.x users upgrade to BIND 9.4-ESV-R1."
If you have to upgrade anyway, but you're going to stick with 9.4.x, why
would you try to "get away with" running something older and
less-recommended in that generation of BIND 9 than 9.4-ESV-R1?
