Bugzilla:
1311438: CVE-2016-2513 python-django: User enumeration through timing difference on password hasher work factor upgrade
A timing attack flaw was found in the way Django's PBKDF2PasswordHasher performed password hashing. Passwords hashed with an older version of PBKDF2PasswordHasher used less hashing iterations, and thus allowed an attacker to enumerate existing users based on the time differences in the login requests.
