CVE-2007-1420: MySQL

Low severity, CVSS 2.1. EPSS: 1% chance of exploitation in the next 30 days.

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.
