Javier Fernandez-Sanguino Pena from the Debian Security Audit
Project discovered that the 'mysqlaccess' script creates temporary
files in world-writeable directories with predictable names.
</p>
</description>
<impact type="normal">
<p>
A local attacker could create symbolic links in the temporary
files directory, pointing to a valid file somewhere on the filesystem.
When the mysqlaccess script is executed, this would result in the file
being overwritten with the rights of the user running the software,
which could be the root user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All MySQL users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-db/mysql-4.0.22-r2&quot;</code>
</resolution>
