The mysqlhotcopy script in mysql 4.0.20 and earlier, when using the scp method from the mysql-server package, allows local users to overwrite arbitrary files via a symlink attack on temporary files.
Stack-based buffer overflow in the mysql_real_connect function in the MySql client library (libmysqlclient) 4.0.13 and earlier allows local users to execute arbitrary code via a long socket name, a different vulnerability than CVE-2001-1453.
MySQL 3.20 through 4.1.0 uses a weak algorithm for hashed passwords, which makes it easier for attackers to decrypt the password via brute force methods.
Buffer overflow in get_salt_from_password from sql_acl.cc for MySQL 4.0.14 and earlier, and 3.23.x, allows attackers with ALTER TABLE privileges to execute arbitrary code via a long Password field.
MySQL 3.23.55 and earlier creates world-writeable files and allows mysql users to gain root privileges by using the "SELECT * INFO OUTFILE" operator to overwrite a configuration file and cause mysql to run as root upon restart, as demonstrated by modifying my.cnf.
Double-free vulnerability in mysqld for MySQL before 3.23.55 allows attackers with MySQL access to cause a denial of service (crash) via mysql_change_user.
The default configuration of the Windows binary release of MySQL 3.23.2 through 3.23.52 has a NULL root password, which could allow remote attackers to gain unauthorized root access to the MySQL database.
The default configuration of MySQL 3.20.32 through 3.23.52, when running on Windows, does set the bind address to the loopback interface, which allows remote attackers to connect to the database.
