Description

Updated openldap packages that fix a security flaw are now available for Red Hat Enterprise Linux 4.

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

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

A flaw was found in the way OpenLDAP's slapd daemon handled malformed objectClasses LDAP attributes. An authenticated local or remote attacker could create an LDAP request which could cause a denial of service by crashing slapd. (CVE-2007-5707)

In addition, the following feature was added: * OpenLDAP client tools now have new option to configure their bind timeout.

All users are advised to upgrade to these updated openldap packages, which contain a backported patch to correct this issue and provide this security enhancement.
