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.

Affected products

Mysql: through 5.0.33; 5.0.0, 5.0.1, 5.0.2, 5.0.3, 5.0.4, 5.0.5 (+7)
MySQL Server: 5.0.6, 5.0.7, 5.0.32, 5.0.41
