CVE-2013-4449

Publication date 5 February 2014

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.
