SCA: security update for gunicorn (GHSA-w3h3-4rj7-4ph4)

high Tenable Self-Hosted Container Security Plugin ID 419657

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling (HRS)
 vulnerabilities. By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass
 security restrictions and access restricted endpoints. This issue is due to Gunicorn's handling of
 Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-
 Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability
 allows for a range of attacks including cache poisoning, session manipulation, and data exposure.
 (CVE-2024-1135)
