MGASA-2024-0236 - Updated python-gunicorn packages fix security vulnerability

Publication date: 24 Jun 2024
URL: https://advisories.mageia.org/MGASA-2024-0236.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2024-1135

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.
