Описание

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, a response with an excessive number of multipart headers may be allowed to use more memory than intended, potentially allowing a DoS vulnerability. This issue has been patched in version 3.13.4.

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for asyncio and Python. A remote attacker could exploit this vulnerability by sending a response with an excessive number of multipart headers. This could cause the system to consume more memory than intended, leading to a Denial of Service (DoS) condition.

Отчет

The availability impact of this flaw does not pose a risk to host Red Hat systems.

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.
