Description:
A vulnerability has been identified in MySQL, which can be exploited by malicious users to escalate their privileges on a vulnerable system.
The vulnerability is caused due to a boundary error when checking passwords before hashing and storing them in the "User" table. This can be exploited to cause a buffer overflow by supplying a value longer than 16 characters using "set password".
Successful exploitation allows malicious MySQL users with "ALTER" privileges to execute arbitrary code on the system with the privileges of the MySQL server.
The vulnerability has been reported in versions 4.0.14 and 3.0.57. However, prior versions may also be affected.
Solution:
Update to version 4.0.15:
