Synopsis
========

A vulnerability in MySQL might allow users to bypass privileges and
gain access to other databases.

Background
==========

MySQL is a popular multi-threaded, multi-user SQL server.

Affected packages
=================

    -------------------------------------------------------------------
     Package       /   Vulnerable   /                       Unaffected
    -------------------------------------------------------------------
  1  dev-db/mysql      < 5.0.60-r1                        >= 5.0.60-r1

Description
===========

Sergei Golubchik reported that MySQL imposes no restrictions on the
specification of "DATA DIRECTORY" or "INDEX DIRECTORY" in SQL "CREATE
TABLE" statements.

Impact
======

An authenticated remote attacker could create MyISAM tables, specifying
DATA or INDEX directories that contain future table files by other
database users, or existing table files in the MySQL data directory,
gaining access to those tables.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MySQL users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.60-r1"
