Red Hat Security Advisory 2012-0899-04

Red Hat Security Advisory 2012-0899-04
Posted Jun 20, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0899-04 - OpenLDAP is an open source suite of LDAP applications and development tools. A denial of service flaw was found in the way the OpenLDAP server daemon 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. 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.

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
