Description

Updated openldap packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

A denial of service flaw was found in the way the OpenLDAP server daemon (slapd) processed certain search queries requesting only attributes and no values. In certain configurations, a remote attacker could issue a specially crafted LDAP search query that, when processed by slapd, would cause slapd to crash due to an assertion failure. (CVE-2012-1164)

These updated openldap packages include numerous bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes.

Users of OpenLDAP are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the OpenLDAP daemons will be restarted automatically.
