From secunia security advisory at $URL:

Description:
The vulnerability is caused due to an assertion error when processing certain search results and can be exploited via a LDAP search request with "attrsOnly" set to true (e.g. ldapsearch -A).

Successful exploitation requires a proxy server configured to use both a relay backend and a translucent overlay.

The vulnerability is reported in versions prior to 2.4.30.


Solution
Update to version 2.4.30.

CVE-2012-1164 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1164):
  slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of
  service (assertion failure and daemon exit) via an LDAP search query with
  attrsOnly set to true, which causes empty attributes to be returned.
