Descriptions
An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().
USN-7501-1 fixed a vulnerability in Django. This update provides the corresponding update for Ubuntu 18.04 LTS. Elias Myllymäki discovered that Django incorrectly handled stripping large sequences of incomplete HTML tags. A remote attacker could possibly use this issue to cause Django to consume resources, leading to a denial of service.
