CVE Request -- openldap (slapd): Assertion failure by processing search queries requesting only attributes for particular entry

Hello Kurt, Steve, vendors,

  a denial of service flaw was found in the way the slapd server of the OpenLDAP,
the Lightweight Directory Access Protocol applications and development suite,
processed certain search queries requesting only attributes (no values) for a
particular entry. A remote attacker could issue a specially-crafted LDAP search
query, which once processed by a vulnerable slapd server would lead to
assertion failure (slapd abort).
