+  * SECURITY:
+    Fix for CVE-2007-5925: The convert_search_mode_to_innobase function in
+    ha_innodb.cc in the InnoDB engine in MySQL 5.1.23-BK and earlier allows
+    remote authenticated users to cause a denial of service (database crash)
+    via a certain CONTAINS operation on an indexed column, which triggers an
+    assertion error. (closes: #451235)
