How to fix?

Upgrade Debian:10 python2.7 to version 2.7.16-2+deb10u3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2.7 package and not the python2.7 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1, 3.9.5, 3.8.11, 3.7.11 and 3.6.14.
