Description:
  Evgeny Legerov discovered [0] a vendor-confirmed [1] Denial-of-Service
  (DoS) vulnerability in OpenLDAP [2]. 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 [3] to the problem.
