Background ========= phpMyAdmin is a web-based management tool for MySQL databases. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-db/phpmyadmin < 4.0.10.20 > = 4.0.10.20 < 4.7.0 > = 4.7.0 Description ========== 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). This behavior depends on the PHP version used (it seems PHP 5 is affected, while PHP 7.0 is not). Impact ===== A remote attacker, who only needs to know the username, could bypass security restrictions and access phpMyAdmin. Workaround ========= Set a password for all users. Resolution ========= All phpMyAdmin 4.0.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v "> =dev-db/phpmyadmin-4.0.10.20:4.0.10.20" All otherphpMyAdmin users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-db/phpmyadmin-4.7.0:4.7.0" References ========= [ 1 ] PMASA-2017-8 https://www.phpmyadmin.net/security/PMASA-2017-8/ Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201707-03 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
