Multiple vulnerabilities have been identified in MySQL, which could be exploited by malicious users to bypass security checks or obtain sensitive information.
The first issue is caused by an error when invoking a stored routine declared using SQL SECURITY INVOKER, which could be exploited by authenticated attackers to bypass security restrictions and gain elevated privileges.
The second vulnerability is caused by an error in the "mysql_execute_command()" function that does not properly validate users privilege when executing a RENAME TABLE command, which could be exploited by malicious users, without DROP privileges, to rename arbitrary tables.
The third issue is caused by an error when displaying error messages, which could be exploited by a malicious user with "ALTER" privileges on a partitioned table to obtain certain information that should normally require "SELECT" privileges.
