Ubuntu Security Notice 2622-1 - It was discovered that OpenLDAP incorrectly handled certain search queries that returned empty attributes. A remote attacker could use this issue to cause OpenLDAP to assert, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. Michael Vishchers discovered that OpenLDAP improperly counted references when the rwm overlay was used. A remote attacker could use this issue to cause OpenLDAP to crash, resulting in a denial of service. Various other issues were also addressed.

Red Hat Security Advisory 2014-0206-01 - 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.

Mandriva Linux Security Advisory 2014-026 - 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 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. The updated packages have been patched to correct this issue.
