Scientific Linux Security Update : openldap on SL6.x i386/x86_64

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


Synopsis :

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

Description :

A denial of service flaw was found in the way the OpenLDAP server
daemon (slapd) performed reference counting when using the rwm
(rewrite/remap) overlay. A remote attacker able to query the OpenLDAP
server could use this flaw to crash the server by immediately
unbinding from the server after sending a search request.
(CVE-2013-4449)

This update also fixes the following bug :

- Previously, OpenLDAP did not properly handle a number of
simultaneous updates. As a consequence, sending a number
of parallel update requests to the server could cause a
deadlock. With this update, a superfluous locking
mechanism causing the deadlock has been removed, thus
fixing the bug.
