OpenLDAP slapd RWM Overlay Use-After-Free Denial Of Service Vulnerability

Publish date: July 21, 2015
  Severity: MEDIUM
  CVE Identifier: 2013-4449
  Advisory Date: JUL 21, 2015

  DESCRIPTION

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.
