Description

A updated openldap packages that fix a security flaw and a memory leak bug are now available for Red Hat Enterprise Linux 3.

This update has been rated as having low security impact by the Red Hat Security Response Team.

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.
