Echo: aiohttp: security update to 3.9.2

medium Tenable Cloud Security Plugin ID 462303

Description

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

 - aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Security-sensitive parts
 of the Python HTTP parser retained minor differences in allowable character sets, that must trigger error
 handling to robustly match frame boundaries of proxies in order to protect against injection of additional
 requests. Additionally, validation could trigger exceptions that were not handled consistently with
 processing of other malformed input. Being more lenient than internet standards require could, depending
 on deployment environment, assist in request smuggling. The unhandled exception could cause excessive
 resource consumption on the application server and/or its logging facilities. This vulnerability exists
 due to an incomplete fix for CVE-2023-47627. Version 3.9.2 fixes this vulnerability. (CVE-2024-23829)

Solution

Update the aiohttp library and its related packages to version 3.9.2 or later.
