View online: https://www.drupal.org/sa-contrib-2018-077 Project: Password Policy [1] Version: 7.x-1.x-dev Date: 2018-December-05 Security risk: *Less critical* 9∕25 AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:Default [2] Vulnerability: Denial of Service Description:  The Password Policy module makes it possible to set constraints on user passwords which disallow certain passwords. The "digit placement" constraint is vulnerable to Denial of Service attacks if an attacker submits specially crafted passwords which can cause a site to become unresponsive. This vulnerability is mitigated by the fact that a site must have the "digit placement" constraint enabled. Solution:  Install the latest version: * If you use the Password Policy module for Drupal 7.x, upgrade to Password Policy 7.x-1.16 [3] Reported By:  * Michael Sherron [4] Fixed By:  * AohRveTPV [5] Coordinated By:  * Greg Knaddison [6] of the Drupal Security Team * David Snopek [7] of the Drupal Security Team [1] https://www.drupal.org/project/password_policy [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/password_policy/releases/7.x-1.16 [4] https://www.drupal.org/user/470070 [5] https://www.drupal.org/user/2760115 [6] https://www.drupal.org/u/greggles [7] https://www.drupal.org/u/dsnopek
