1. Problem Description

   There is a buffer overflow in the MySQL server that allows
   an attacker to gain access to the mysql account. A valid mysql account
   is required for this attack. An exploit for this problem has been
   published on bugtraq.

   Note that a second vulnerability is currently being discussed
   on various mailing lists relating to the SHOW GRANTS command.
   This command is not supported in MySQL versions currently shipped
   by Caldera, so this second vulnerability does not affect OpenLinux.
