Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The rwm overlay does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search.
