A vulnerability in the Certificate List Exact Assertion validation
was discovered in OpenLDAP, a free implementation of the Lightweight
Directory Access Protocol. An unauthenticated remote attacker can
take advantage of this flaw to cause a denial of service (slapd
daemon crash) via specially crafted packets.
