Scientific Linux Security Update : bind on SL5.x, SL6.x i386/x86_64

This script is Copyright (C) 2012 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 zero length resource data
records. 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 crash or, possibly, disclose
portions of its memory. (CVE-2012-1667)

A flaw was found in the way BIND handled the updating of cached name
server (NS) resource records. A malicious owner of a DNS domain could
use this flaw to keep the domain resolvable by the BIND server even
after the delegation was removed from the parent DNS zone. With this
update, BIND limits the time-to-live of the replacement record to that
of the time-to-live of the record being replaced. (CVE-2012-1033)

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.
