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


Django accounts could be hijacked through password reset requests.

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


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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.10:
python-django 1:1.11.22-1ubuntu1.1
python3-django 1:1.11.22-1ubuntu1.1

Ubuntu 19.04:
python-django 1:1.11.20-1ubuntu0.3
python3-django 1:1.11.20-1ubuntu0.3

Ubuntu 18.04 LTS:
python-django 1:1.11.11-1ubuntu1.6
python3-django 1:1.11.11-1ubuntu1.6

Ubuntu 16.04 LTS:
python-django 1.8.7-1ubuntu5.11
python3-django 1.8.7-1ubuntu5.11

In general, a standard system update will make all the necessary changes.
