Scientific Linux Security Update : bind on SL5.x i386/x86_64

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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. 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.
