Multiple SQL injection flaws were found in the way the binlog functionality (routines producing events describing database changes such as table creation operations or changes to table data) of MySQL, a multi-user, multi-threaded SQL database server, performed sanitization of table names and other fields prior creating particular log entry. Authorised database users (with privilege to modify tables) could use this flaw to inject arbitrary SQL query into subsequently generated binlog entries.
