Vulnerability from github – Published: 2024-11-18 21:02 – Updated: 2024-11-19 20:48

Summary

aiohttp has a memory leak when middleware is enabled when requesting a resource with a non-allowed method

Details

Summary

A memory leak can occur when a request produces a MatchInfoError. This was caused by adding an entry to a cache on each request, due to the building of each MatchInfoError producing a unique cache entry.

Impact

If the user is making use of any middlewares with aiohttp.web then it is advisable to upgrade immediately.

An attacker may be able to exhaust the memory resources of a server by sending a substantial number (100,000s to millions) of such requests.

CVE-2024-52303 (GCVE-0-2024-52303)

Vulnerability from cvelistv5 – Published: 2024-11-18 20:08 – Updated: 2024-11-19 14:45

Summary

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions starting with 3.10.6 and prior to 3.10.11, a memory leak can occur when a request produces a MatchInfoError. This was caused by adding an entry to a cache on each request, due to the building of each MatchInfoError producing a unique cache entry. An attacker may be able to exhaust the memory resources of a server by sending a substantial number (100,000s to millions) of such requests. Those who use any middlewares with aiohttp.web should upgrade to version 3.10.11 to receive a patch.

Severity ?

8.7 (High)
