openldap security update

CentOS Errata and Security Advisory CESA-2007:0430

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications, libraries and development tools.

A flaw was found in the way OpenLDAP handled selfwrite access. Users with
selfwrite access were able to modify the distinguished name of any user.
Users with selfwrite access should only be able to modify their own
distinguished name. (CVE-2006-4600)

A memory leak bug was found in OpenLDAP’s ldap_start_tls_s() function. An
application using this function could result in an Out Of Memory (OOM)
condition, crashing the application.

All users are advised to upgrade to this updated openldap package,
which contains a backported fix and is not vulnerable to these issues.
