NVD Description

Note: Versions mentioned in the description apply only to the upstream python39-oci-sdk-docs package and not the python39-oci-sdk-docs package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, during cleanup it is possible for a compressed request body to be decompressed into memory in one chunk. An attacker may be able to send a compressed payload in specific situations that could be decompressed into memory, potentially leading to DoS (a zip bomb edge case). This vulnerability is fixed in 3.14.1.
