Scientific Linux Security Update : bind for SL 3.0.x on i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

CVE-2009-0696 bind: DoS (assertion failure) via nsupdate packets

A flaw was found in the way BIND handles dynamic update message
packets containing the 'ANY' record type. A remote attacker could use
this flaw to send a specially crafted dynamic update packet that could
cause named to exit with an assertion failure. (CVE-2009-0696)

Note: even if named is not configured for dynamic updates, receiving
such a specially crafted dynamic update packet could still cause named
to exit unexpectedly.

This update also fixes the following bug :

- the following message could have been logged:
'internal_accept: fcntl() failed: Too many open files'.
With these updated packages, timeout queries are aborted
in order to reduce the number of open UDP sockets, and
when the accept() function returns an EMFILE error
value, that situation is now handled gracefully, thus
resolving the issue. (BZ#498164)

After installing the update, the BIND daemon (named) will be restarted
