Description:
Multiple vulnerabilities have been reported in MySQL, which can be exploited by malicious users to bypass certain security restrictions or cause a DoS (Denial of Service).
1) An error in "ALTER TABLE ... RENAME" operations causes the CREATE/INSERT rights of old tables to be checked, which potentially can be exploited to bypass some applied security restrictions.
The vulnerability has been reported in version 3.23. Other versions may also be affected.
2) It is possible to crash or stall the server when multiple threads ALTER the same or different MERGE tables to change the UNION.
The vulnerability has been reported in version 3.23 and 4.0.18. Other versions may also be affected.
3) It is possible to crash the MySQL server via a specially crafted SELECT statement containing a double quote in an AGAINST function.
The vulnerability has been reported in version 4.0.20. Other versions may also be affected.
4) An error when checking privileges can be exploited under certain conditions to grant privileges on a database, which the user has no privileges on.
The vulnerability has been reported in version 4.0.20. Other versions may also be affected.
Solution:
Update to version 3.23.59 or 4.0.21.
