Overview

gunicorn is a Python WSGI HTTP Server for UNIX

Affected versions of this package are vulnerable to Improper Input Validation. Gunicorn fails with a 500, instead of a 400, when a request path is a malformed IPv6 address. This is due to no raise 'InvalidRequestLine' exception when the line contains malicious data.

Remediation

Upgrade gunicorn to version 19.4.0 or higher.
