CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
MySQL 4.x
http://secunia.com/product/404/

DESCRIPTION:
Eric Romang has reported a vulnerability in MySQL, which can be
exploited by malicious, local users to conduct various actions on a
vulnerable system with escalated privileges.

The vulnerability is caused due to the mysql_install_db script
creating the temporary file "mysql_install_db.$$" insecurely. This
can be exploited to overwrite arbitrary files with the privileges of
the user running the vulnerable script via symlink attacks or execute
arbitrary SQL commands by manipulating the file's contents.

The vulnerability has been reported in versions 4.1.11 and prior and
development release 5.0.4 and prior.

SOLUTION:
Update to version 4.1.12.
