Summary

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:
* 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. (BZ#857056)
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.
