Описание

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, for some multipart form fields, aiohttp read the entire field into memory before checking client_max_size. This issue has been patched in version 3.13.4.

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for Python. A remote attacker could exploit this vulnerability by sending a specially crafted multipart form field. The framework would read the entire field into memory before enforcing size limits, potentially leading to excessive memory consumption and a Denial of Service (DoS) for the affected system.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
