Описание
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, if an attacker sends large incomplete websocket frame payloads, it may be possible to bypass the usual size limits on memory use. This vulnerability is fixed in 3.14.1.
A flaw was found in aiohttp, an asynchronous HTTP client/server framework. An attacker can exploit this vulnerability by sending large, incomplete websocket frame payloads. This can bypass normal memory usage limits, potentially leading to a Denial of Service (DoS) where the affected system becomes unavailable.
Отчет
This vulnerability is rated Moderate because an unauthenticated remote attacker can trigger denial of service against an affected aiohttp HTTP server with WebSocket endpoints by sending large incomplete WebSocket frame payloads that bypass memory size limits. Exploitation requires aiohttp deployed as a network-facing HTTP server that exposes WebSocket endpoints to untrusted clients. Many Red Hat products ship aiohttp as a bundled dependency for client libraries, internal automation, or services that do not expose WebSocket listeners to untrusted users. In those configurations, practical risk may be lower, but affected packages should still be updated to aiohttp 3.14.1 or later when fixes are released.
Меры по смягчению последствий
Update the aiohttp package to version 3.14.1 or later. Until updated builds are available, reduce exposure by not exposing aiohttp-based HTTP servers with WebSocket endpoints directly to untrusted networks. A reverse proxy or load balancer in front of the service can help limit abusive WebSocket traffic. Installations that use aiohttp only as an HTTP client, or that do not expose WebSocket endpoints, are not affected by this flaw.
