| Doc Text: |
A flaw was found in aiohttp. A malicious server can cause a Denial of Service (DoS) through excessive memory and CPU consumption by returning responses with crafted cookie headers. The HTTP client fails to enforce limits on the total number of cookies stored or transmitted, and incorrectly parses unrecognized cookie attributes as separate cookies. This allows a remote server to force the client to accumulate an excessively large cookie set, exhausting system resources during redirects and generating oversized headers for subsequent requests.
