Scientific Linux Security Update : bind-dyndb-ldap on 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 dynamic LDAP back end is a plug-in for BIND that provides back-end
capabilities to LDAP databases. It features support for dynamic
updates and internal caching that help to reduce the load on LDAP
servers.

A flaw was found in the way bind-dyndb-ldap performed the escaping of
names from DNS requests for use in LDAP queries. A remote attacker
able to send DNS queries to a named server that is configured to use
bind-dyndb-ldap could use this flaw to cause named to exit
unexpectedly with an assertion failure. (CVE-2012-3429)

All bind-dyndb-ldap users should upgrade to this updated package,
which contains a backported patch to correct this issue. For the
update to take effect, the named service must be restarted.
