Evgeny Legerov discovered  a vendor-confirmed  Denial-of-Service
(DoS) vulnerability in OpenLDAP . The vulnerability allows remote
attackers to cause a DoS via a certain combination of LDAP "Bind"
requests that trigger an assertion failure in "libldap". The flaw is
caused by incorrectly computing the length of a normalized name. The
Common Vulnerabilities and Exposures (CVE) project assigned the id
CVE-2006-5779  to the problem.
