The password hashing API in Drupal 7.x before 7.34 and the Secure Password Hashes (aka phpass) module 6.x-2.x before 6.x-2.1 for Drupal allows remote attackers to cause a denial of service (CPU and memory consumption) via a crafted request.
libraries/common.inc.php in phpMyAdmin 4.0.x before 4.0.10.7, 4.1.x before 4.1.14.8, and 4.2.x before 4.2.13.1 allows remote attackers to cause a denial of service (resource consumption) via a long password.
wp-includes/class-phpass.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to cause a denial of service (CPU consumption) via a long password that is improperly handled during hashing, a similar issue to CVE-2014-9016.
