Description

From Red Hat Security Advisory 2008:0110 :

Updated openldap packages that fix security issues are now available for Red Hat Enterprise Linux 4 and 5.

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

OpenLDAP is an open source suite of Lightweight Directory Access Protocol (LDAP) applications and development tools. LDAP is a set of protocols for accessing directory services.

These updated openldap packages fix a flaw in the way the OpenLDAP slapd daemon handled modify and modrdn requests with NOOP control on objects stored in a Berkeley DB (BDB) storage backend. An authenticated attacker with permission to perform modify or modrdn operations on such LDAP objects could cause slapd to crash. (CVE-2007-6698, CVE-2008-0658)

Users of openldap should upgrade to these updated packages, which contain a backported patch to correct this issue.
