DESCRIPTION:
Two weaknesses have been reported in the Secure Password Hashes
(phpass) module for Drupal, which can be exploited by malicious
people to conduct brute force attacks and bypass certain security
restrictions.

1) An error in password reset links does not replace the "pass"
attribute in password reset links and can be exploited to determine
reset links via brute force attacks.

2) The application does not invalidate the password reset link once a
user changes the password and can be exploited to gain access to a
user's account.

The weaknesses are reported in versions prior to 5.x-1.5 and 6.x-1.1.

SOLUTION:
Update to a fixed version.
