bind bug fix and enhancement update

Updated bind packages that fix several bugs and add various enhancements are now
available for Red Hat Enterprise Linux 6.

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain
Name System) protocols. BIND includes a DNS server (named), which resolves host
names to IP addresses; a resolver library (routines for applications to use when
interfacing with DNS); and tools for verifying that the DNS server is operating
properly.

These updated bind packages include numerous bug fixes and enhancements. Space
precludes documenting all of these changes in this advisory. Users are directed
to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most
significant of these changes:

All users of bind are advised to upgrade to these updated packages, which
provide numerous bug fixes and enhancements.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
