SCA: security update for aiohttp (GHSA-45c4-8wx5-qw6w)

medium Tenable Cloud Security Plugin ID 409957

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. aiohttp v3.8.4 and earlier
are bundled with llhttp v6.0.6. Vulnerable code is used by aiohttp for its HTTP request parser when
available which is the default case when installing from a wheel. This vulnerability only affects users of
aiohttp as an HTTP server (ie `aiohttp.Application`), you are not affected by this vulnerability if you
are using aiohttp as an HTTP client library (ie `aiohttp.ClientSession`). Sending a crafted HTTP request
will cause the server to misinterpret one of the HTTP header values leading to HTTP request smuggling.
This issue has been addressed in version 3.8.5. Users are advised to upgrade. Users unable to upgrade can
reinstall aiohttp using `AIOHTTP_NO_EXTENSIONS=1` as an environment variable to disable the llhttp HTTP
request parser implementation. The pure Python implementation isn't vulnerable. (CVE-2023-37276)
