python-aiohttp: aiohttp is an asynchronous HTTP client/server framework for asyncio and Python
CVE-2024-52303 is fixed in python-aiohttp on 1 platform, first by DEBIAN-CVE-2024-52303, released November 18, 2024. It is not reported as exploited. Patch Radar priority: Routine.
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.
