Descriptions

The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier 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.

El overlay rwm en OpenLDAP 2.4.23, 2.4.36 y anteriores no cuenta debidamente las referencias, lo que permite a atacantes remotos causar una denegación de servicio (caída de slapd) mediante la desvinculación inmediata después de una solicitud de búsqueda, lo que provoca que rwm_conn_destroy libere la sesión mientras que está siendo utilizado por rwm_op_search.

OpenLDAP is an open source suite of Lightweight Directory Access Protocol applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap package contains configuration files, libraries, and documentation for OpenLDAP. A denial of service flaw was found in the way the OpenLDAP server daemon performed reference counting when using the rwm overlay. A remote attacker able to query the OpenLDAP server could use this flaw to crash the server by immediately unbinding from the server after sending a search request.
