NVD Description

Note: Versions mentioned in the description apply to the upstream python-django package. See Remediation section below for Ubuntu:16.04 relevant versions.

An issue was discovered in Django 1.11.x before 1.11.23, 2.1.x before 2.1.11, and 2.2.x before 2.2.4. If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable.

Remediation

Upgrade Ubuntu:16.04 python-django to version 1.8.7-1ubuntu5.10 or higher.
