Your bind is likely up to date. But you can update it either via WHM Update System Software or WHM Update Server Software [i forgot off the top of my head].
Or you can do it manually from commandline using yum.
But, if it's the up-to-date version for your particular OS distro, it isn't going to update any further.
Why are you asking? Do you have a PCI Compliance place stating that you have a problematic install of BIND? If so, you can do this [from commandline] to see if your version of installed Bind is patched for whatever security issue the PCI place may be complaining about.
rpm -q --changelog bind
If your version of bind claims to have resolved whatever issue the PCI folks are barking about, then send them the output of the command above and tell them that it's a non-issue.
