Django is a high-level Python Web framework that encourages rapid developmentand a clean, pragmatic design.
It focuses on automating as much as possible andadhering to the DRY (Don’t Repeat Yourself) principle.Security Fix(es):* An open-redirect flaw was found in the way Django’sdjango.utils.http.is_safe_url() function filtered authentication URLs.
Anattacker able to trick a victim into visiting a crafted URL could use this flawto redirect that victim to a malicious site. (CVE-2016-2512)* A timing attack flaw was found in the way Django’s PBKDF2PasswordHasherperformed password hashing. Passwords hashed with an older version ofPBKDF2PasswordHasher used less hashing iterations, and thus allowed an attackerto enumerate existing users based on the time differences in the login requests.(CVE-2016-2513)Red Hat would like to thank the Django project for reporting these issues.
