FKIE_CVE-2013-4449
Vulnerability from fkie_nvd - Published: 2014-02-05 18:55 - Updated: 2026-06-16 23:57
Severity
Summary
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.
