Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The deref_parseCtrl function in servers/slapd/overlays/deref.c allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an empty attribute list in a deref control in a search request.
