The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.
A flaw was found in the way BIND handled resource records with a large RDATA value. A malicious owner of a DNS domain could use this flaw to create specially crafted DNS resource records, that would cause a recursive resolver or secondary server to exit unexpectedly with an assertion failure. (CVE-2012-4244)
This update also fixes the following bug :

This update also fixes the following bug :
- The bind-chroot-admin script, executed when upgrading
the bind-chroot package, failed to correctly update the
permissions of the /var/named/chroot/etc/named.conf
file. Depending on the permissions of the file, this
could have prevented named from starting after
installing package updates. With this update,
bind-chroot-admin correctly updates the permissions and
ownership of the file. Users of bind are advised to
upgrade to these updated packages, which correct these
issues. After installing the update, the BIND daemon
(named) will be restarted automatically."
