Scientific Linux Security Update : openldap on SL6.x i386/x86_64 (20140203)

medium Nessus Plugin ID 72276

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.

Solution

Update the affected packages.
