Security Fix

CVE-2013-4449
A denial of service flaw was found in the way the OpenLDAP server daemon (slapd) performed reference counting when using the rwm (rewrite/remap) 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.
Red Hat would like to thank Michael Vishchers from Seven Principles AG for reporting this issue.
All openldap users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Bug Fix

BZ#1096634
Previously, the replication process in LDAP did not function correctly. As a consequence, replicated data could be inconsistent and, under some circumstances, the Stand-alone LDAP Daemon, slapd, terminated unexpectedly. With this update, LDAP has been modified to properly lock critical sections. Therefore, the replicated data now stays consistent and slapd no longer crashes.
Users of openldap are advised to upgrade to these updated packages, which fix this bug.
