<background>
<p>phpMyAdmin is a web-based management tool for MySQL databases.</p>
</background>
<description>
<p>A vulnerability was discovered where the restrictions caused by
“$cfg[‘Servers’][$i][‘AllowNoPassword’] = false” are bypassed
under certain PHP versions. This can lead compromised user accounts, who
have no passwords set, even if the administrator has set
“$cfg[‘Servers’][$i][‘AllowNoPassword’]” to false (which is
the default).
</p>
<p>This behavior depends on the PHP version used (it seems PHP 5 is
affected, while PHP 7.0 is not).
</p>
</description>
<impact type="normal">
<p>A remote attacker, who only needs to know the username, could bypass
security restrictions and access phpMyAdmin.
</p>
</impact>
<workaround>
<p>Set a password for all users.</p>
</workaround>
<resolution>
<p>All phpMyAdmin 4.0.x users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose
">=dev-db/phpmyadmin-4.0.10.20:4.0.10.20"
</code>
<p>All other phpMyAdmin users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/phpmyadmin-4.7.0:4.7.0"
</code>
</resolution>
