[Security-news] SA-CONTRIB-2011-026 - Secure Password Hashes (phpass) - Multiple Vulnerabilities

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-026
  * Project: Secure Password Hashes (phpass) [1] (third-party module)
  * Version: 5.x, 6.x
  * Date: 2011-June-29
  * Security risk: Critical [2]
  * Exploitable from: Remote
  * Vulnerability: Multiple vulnerabilities

-------- DESCRIPTION  
---------------------------------------------------------

This module uses the
PHPass
hashing library to try to store users hashed passwords securely.

The module sets a fixed string for the 'pass' column in the {users} database
column but does no replace the pass attribute of the account object used for
password reset links. This leads to as a vulnerability where password reset
links could be determined using a brute force attack within a matter of
minutes in the worst case. In addition, password reset link is not
invalidated if a logged-in user changes her password.
