(Insecure Temporary File Creation In MySQL)
The MySQL bug reporting utility (mysqlbug) creates a temporary file to log
bug reports to. A malicious local user with write access to the /tmp
directory could create a symbolic link of the name mysqlbug-N
pointing to a protected file, such as /etc/passwd, such that when mysqlbug
creates the Nth log file, it would end up overwriting the target
file. A similar vulnerability exists with the mysql_multi utility, which
creates a temporary file called mysql_multi.log.
Impact
Since mysql_multi runs as root, a local attacker could use this to destroy
any other users\' data or corrupt and destroy system files.
Workaround
One could modify both scripts to log to a directory that users do not have
write permission to, such as /var/log/mysql/.

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0388
Solution:
All users should upgrade to the latest stable version of MySQL.
# emerge sync
# emerge -pv ">=dev-db/mysql-4.0.18-r2"
# emerge ">=dev-db/mysql-4.0.18-r2"
Risk factor : Medium
