Vulnerability CVE-2007-1420
Published: 2007-03-12   Modified: 2012-02-12

Description:
MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing information_schema table subselects and using ORDER BY to sort a single-row result, which prevents certain structure elements from being initialized and triggers a NULL dereference in the filesort function.
