CVE-2024-52303

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.

Summary		(es) aiohttp es un framework de trabajo de cliente/servidor HTTP asincrónico para asyncio y Python. En las versiones a partir de la 3.10.6 y anteriores a la 3.10.11, puede producirse una pérdida de memoria cuando una solicitud produce un MatchInfoError. Esto se debía a que se añadía una entrada a una memoria caché en cada solicitud, debido a que la creación de cada MatchInfoError producía una entrada de memoria caché única. Un atacante podría agotar los recursos de memoria de un servidor enviando una cantidad sustancial (entre cientos y millones) de dichas solicitudes. Quienes utilicen cualquier middleware con aiohttp.web deberían actualizar a la versión 3.10.11 para recibir un parche.
