Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10 - Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

Django accounts could be hijacked through password reset requests.

Software Description: - python-django: High-level Python web development framework

Details:

Simon Charette discovered that the password reset functionality in Django used a Unicode case insensitive query to retrieve accounts associated with an email address. An attacker could possibly use this to obtain password reset tokens and hijack accounts.

Ubuntu 19.10:
python-django 1:1.11.22-1ubuntu1.1
