Changes in MySQL 5.6.51
Security Notes
The linked OpenSSL library for MySQL Server has been updated to version 1.1.1i. Issues fixed in the new OpenSSL version are described at https://www.openssl.org/news/cl111.txt and https://www.openssl.org/news/vulnerabilities.html.
Bugs Fixed
InnoDB: The full-text search synchronization thread attempted to read a previously-freed word from the index cache.
The server did not handle all cases of the WHERE_CONDITION optimization correctly.
Privileges for some INFORMATION_SCHEMA tables were checked incorrectly.
In certain cases, the server did not handle multiply-nested subqueries correctly.
A buffer overflow in the client library was fixed.
